Overview

This skill has a coherent self-evolution purpose, but it uses high-impact automation with under-disclosed data collection, external publishing, auto-updates, shell execution, and destructive rollback behavior.

Install only in an isolated disposable workspace with no secrets or valuable uncommitted work. Disable auto-publish, auto-issue reporting, proactive questions, auto-update, loop mode, and hard rollback unless you have reviewed the exact outbound data and recovery behavior. Rotate the hardcoded A2A secret before any use.

• Location: run_evolver.sh:2
• Finding: Hardcoded A2A Authentication Secret in Executable Launcher<![CDATA[ ## Vulnerability Details **File Location**: `run_evolver.sh:2-8` **Vulnerability Type**: Hardcoded credential **Risk Level**: Critical ### Vulnerable Code ```sh cd /home/openclaw/.openclaw/workspace_roamer_alcor/skills/alcor-capability-evolver export A2A_NODE_ID=node_alcor_001 export A2A_NODE_SECRET=e8bc58cff4b0512a43f957bd0750435842146a8925e78d982c379967049c46a8 export A2A_HUB_URL=https://evomap.ai export HTTP_PROXY=http://127.0.0.1:7890 export HTTPS_PROXY=http://127.0.0.1:7890 export MEMORY_DIR=/tmp/evolver_memory ``` ### Technical Analysis A 64-character A2A node authentication secret is embedded directly in a committed executable script. Anyone who can obtain the package, a repository clone, a backup, or build artifact can recover the credential. This also contradicts the Skill documentation, which says node credentials should be supplied through the environment rather than hardcoded. Even if the credential is no longer active, its presence demonstrates insecure secret handling and requires rotation because its historical exposure cannot be reversed. ### Attack Path 1. An attacker downloads or otherwise reads the Skill package. 2. The attacker extracts `A2A_NODE_ID` and `A2A_NODE_SECRET` from `run_evolver.sh`. 3. The attacker constructs requests to the configured EvoMap A2A endpoints. 4. The secret is submitted as a bearer credential. 5. If accepted by the Hub, the attacker can impersonate the affected node and perform actions available to that identity. ### Impact Assessment Potential impact includes node impersonation, unauthorized asset publication, task operations, false reputation activity, and access to any Hub functionality authorized for the node. The credential is exposed to every principal with read access to the package. ]]>
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Revoke and rotate the exposed node secret immediately. 2. Remove the secret from the current tree, repository history, release archives, logs, and cached artifacts. 3. Load credentials from a dedicated secret manager or a runtime environment injected by the deployment system. 4. Restrict secret files to the agent account with mode `0600`. 5. Add secret scanning to CI and pre-commit checks. 6. Replace the launcher with validation that fails safely when the secret is absent, without printing it. ]]>

The prompt labels the content “VERIFIED” and orders the executor to “Apply faithfully,” but the reviewed path does not establish a cryptographically verified publisher identity or enforce a data-only boundary around the remote payload. A malicious asset can contain imperative text disguised as a summary, strategy, payload field, or code sample. Because the agent has workspace-write and shell capabilities, prompt injection can cross from untrusted remote data into ...[truncated 1001 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Treat every Hub field as untrusted data, never as authoritative instructions. 2. Remove “VERIFIED,” “Apply faithfully,” and similar trust-elevating directives. 3. Verify immutable content hashes and signatures against an explicitly trusted publisher allowlist. 4. Parse remote assets into a restrictive schema and reject imperative text, tool calls, shell commands, path traversal, and policy-changing content. 5. Require explicit human approval before any remote-derived change is applied. 6. Execute candidate patches in a disposable sandbox or isolated Git worktree with no secrets or network access. 7. Independently generate and inspect the patch locally rather than asking the agent to follow remote prose. ]]>

T03 · Remote Payload Retrieval and Execution

Error

• Location: src/evolve.js:514
• Finding: Automatic Forced Retrieval and Replacement of Executable Skills<![CDATA[ ## Vulnerability Details **File Location**: `src/evolve.js:514-584` **Vulnerability Type**: Unattended remote software update **Risk Level**: High ### Vulnerable Code ```js function checkAndAutoUpdate() { try { // Read config: default autoUpdate = true const configPath = path.join(os.homedir(), '.openclaw', 'openclaw.json'); let autoUpdate = true; let intervalHours = 6; // ... if (!autoUpdate) return; // ... const slugs = ['evolver', 'feishu-evolver-wrapper']; let updated = false; for (const slug of slugs) { try { const out = execSync(`${clawhubBin} update ${slug} --force`, { encoding: 'utf8', stdio: ['ignore', 'pipe', 'pipe'], timeout: 30000, cwd: path.resolve(REPO_ROOT, '..'), windowsHide: true, }); // ... } catch (e) { // Non-fatal: update failure should never block evolution } } } catch (e) { console.log(`[AutoUpdate] Check failed (non-fatal): ${e.message}`); } } ``` Non-dry runs invoke it through maintenance: ```js function performMaintenance() { // Auto-update check (rate-limited, non-fatal). checkAndAutoUpdate(); ``` ### Technical Analysis The Skill enables automatic updates by default and runs a forced update command for executable Skill packages. This allows the effective code to change after the audited artifact was approved. The reviewed code does not pin an exact version or independently verify a signed update manifest and expected content hash. The update arguments are currently fixed, so this is not primarily shell injection. The risk is an unattended supply-chain execution channel: compromise of a registry, publisher account, distribution system, or later package release can replace trusted local code. ### Attack Path 1. An attacker compromises a package publisher, package, registry, or update channel. 2. A malicious version is made available under one of the fixed Sk ...[truncated 548 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions 1. Disable automatic updates by default. 2. Require explicit administrator approval before downloading or installing an update. 3. Pin exact versions and expected cryptographic hashes. 4. Verify signed release metadata against a locally configured trust root. 5. Remove `--force` from unattended operations. 6. Download and validate updates in a staging area before atomic installation. 7. Record the old and new versions, signer, hash, and approval identity in an audit log. 8. Do not perform package management as part of routine runtime maintenance. ]]>

Make scope enforcement fail closed; never fall back to global sessions. 3. Remove cross-workspace wildcards and collection of command/configuration logs. 4. Collect structured error counters rather than raw conversation or log content. 5. Require explicit informed consent for each additional data source. 6. Store temporary state in a uniquely created mode-`0700` directory. 7. Apply short retention periods and securely delete temporary aggregates after use. 8. Document every read path accurately in the permission manifest. ]]>

• Finding: Arbitrary Shell Command Execution Through Environment Configuration<![CDATA[ ## Vulnerability Details **File Location**: `src/evolve.js:311-320` **Vulnerability Type**: OS command injection **Risk Level**: High ### Vulnerable Code ```js // Generic Integration Status Check (Decoupled) if (process.env.INTEGRATION_STATUS_CMD) { try { const status = execSync(process.env.INTEGRATION_STATUS_CMD, { encoding: 'utf8', stdio: ['ignore', 'pipe', 'ignore'], timeout: 2000, windowsHide: true, }); if (status.trim()) issues.push(status.trim()); } catch (e) {} } ``` ### Technical Analysis `execSync()` receives the complete value of `INTEGRATION_STATUS_CMD`, causing it to be interpreted by a command shell. There is no executable allowlist, argument validation, escaping, or prohibition on shell metacharacters. Environment values may be influenced through deployment configuration, wrapper scripts, inherited service environments, `.env` content, or another component running with configuration-write access. The project loads `.env` from the repository root, increasing the number of locations from which process configuration can originate. This contradicts the documentation statement that no user-controlled input is passed to a shell. ### Attack Path 1. An attacker gains the ability to modify the runtime environment or loaded `.env` configuration. 2. The attacker sets `INTEGRATION_STATUS_CMD` to an arbitrary shell command. 3. An evolution run invokes `checkSystemHealth()`. 4. `execSync()` passes the value to the system shell. 5. The command runs under the same operating-system identity as the agent. ### Impact Assessment The attacker can execute arbitrary commands with the agent process’s privileges. This may permit reading workspace and agent files, modifying source or memory, accessing environment secrets, making network requests, or deleting data. ]]>

• Location: index.js:30
• Finding: Destructive Git Rollback Can Delete Unrelated Local Work<![CDATA[ ## Vulnerability Details **File Location**: `index.js:30-34, 443-444` **Vulnerability Type**: Unsafe destructive recovery operation **Risk Level**: High ### Vulnerable Code ```js const { execSync } = require('child_process'); execSync('git checkout -- .', { cwd: repoRoot, encoding: 'utf8', timeout: 30000 }); execSync('git clean -fd', { cwd: repoRoot, encoding: 'utf8', timeout: 30000 }); ``` The destructive sequence appears again in a later rollback path: ```js execSync('git checkout -- .', { cwd: repoRoot, encoding: 'utf8', timeout: 30000 }); execSync('git clean -fd', { cwd: repoRoot, encoding: 'utf8', timeout: 30000 }); ``` ### Technical Analysis `git checkout -- .` discards all unstaged tracked changes in the selected repository, while `git clean -fd` recursively removes untracked files and directories. These commands are repository-wide rather than restricted to paths created or modified by the current evolution cycle. Because the Skill operates autonomously by default, a failed validation or rollback can destroy unrelated user work that existed before the cycle. Git tracking does not protect untracked files, and checkout does not preserve uncommitted tracked edits. ### Attack Path 1. A user has unrelated uncommitted changes or untracked files in the repository. 2. The autonomous evolution cycle starts without isolating or snapshotting that work. 3. The cycle reaches a rollback or cleanup path. 4. `git checkout -- .` discards tracked modifications. 5. `git clean -fd` deletes untracked files and directories. 6. The unrelated work becomes unavailable unless separately backed up. An adversarial remote asset could also intentionally induce validation failure to increase the chance that rollback is triggered. ### Impact Assessment The primary impact is repository-wide loss of uncommitted tracked work and untracked files. Depending on repository placement, this can affect source code, generated assets, local configur ...[truncated 68 chars]

Context-Inappropriate Capability

Critical

• Confidence: 99% confidence
• Finding: This code executes whatever command string is present in the INTEGRATION_STATUS_CMD environment variable via execSync. In a skill with shell permission, any actor who can influence environment configuration gains arbitrary command execution, which can lead to data theft, persistence, or full host compromise.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 95% confidence
• Finding: The declared description describes a full self-evolution engine that analyzes runtime history and applies constrained evolution. The supplied code does not do analysis, decision-making, or any evolution step. It only copies and merges local files and logs into a directory, acting as a preprocessing or data-preparation utility. The accessed resources are plausibly related to runtime history, so they are not inherently inconsistent, and the declared shell permission is sufficient. However, the primary purpose is materially narrower and different from the declared behavior, so this is a mismatch.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 96% confidence
• Finding: The declared description suggests a core self-improvement component that evaluates runtime history and applies constrained evolution to an AI agent. The supplied code does not perform analysis, decision-making, or mutation/evolution. Instead, it reads stored genes, capsules, and events, filters exportable assets, formats them as JSON or protocol 'hello'/'publish' messages, and optionally persists/sends those messages via a transport. While the code references evolution-related assets, its primary purpose is asset export/publication, which is materially different from the declared self-evolution engine behavior.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 98% confidence
• Finding: The code does not analyze runtime history, identify agent improvements, or perform any kind of self-evolution. Its primary function is ingestion and staging of externally supplied A2A assets with validation, confidence reduction, storage, and optional decision emission. While the declared permissions include network and shell, the code chunk itself is mainly a data-ingestion/quarantine utility, which is materially different from the declared self-evolution purpose.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 94% confidence
• Finding: The declared description suggests a system that reviews runtime history to discover improvements and then evolves an agent under protocol constraints. The supplied code does not analyze runtime history, evaluate agent performance, or generate improvements. Instead, it is a narrow CLI script for promoting already-existing external candidates into local storage after explicit user selection and validation, with special handling for capsules, genes, and evolution events. While there is some protocol-related behavior via A2A decision emission and some safety gating for gene validation commands, that only supports asset promotion workflows and does not substantiate the broader claimed purpose of a self-evolution engine.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 98% confidence
• Finding: The code is a reporting/analysis utility, not an engine that 'applies protocol-constrained evolution.' It reads evolution_history_full.md, extracts interesting entries, groups them by skill, and writes evolution_detailed_report.md. That aligns with historical summarization, but not with actually identifying and implementing agent improvements in a self-evolving system. There is no network access, shell execution, runtime agent modification, protocol enforcement, or mutation logic in this chunk. While analyzing history is loosely related to the declared description, the primary behavior here is generating a markdown report, making the description materially overstated for this code.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 99% confidence
• Finding: The declared description says the skill is a self-evolution engine for AI agents that analyzes runtime history and applies constrained evolution. The supplied code does none of that. Its primary function is a repository build/release utility: it reads a public manifest, copies included files into an output directory, excludes forbidden files, performs text rewrites, rewrites package.json scripts, derives a suggested SemVer bump from git commit subjects, and writes build metadata and semver notes/prompts to a private memory directory. While one could loosely interpret 'history analysis' as examining git history, the code does not analyze agent runtime behavior or evolve an agent's protocol. The primary purpose is materially different from the declared purpose, so this is a clear mismatch.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 98% confidence
• Finding: The code does not implement a self-evolution engine. It performs offline log extraction: reading a specific log file, parsing lines matching a Feishu send command, attaching timestamps from nearby log markers, deduplicating entries by title, converting timestamps to Asia/Shanghai time, and writing a Markdown summary file. There is no mechanism for identifying improvements, modifying agent behavior, applying any protocol constraints, invoking shell commands, or performing network actions. While over-declared permissions alone are not a mismatch, the primary purpose here is materially different from the declared description.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 97% confidence
• Finding: The declared description suggests an active self-evolution system for AI agents that inspects runtime history and applies constrained improvements. The supplied code does none of that. It is a reporting utility that reads version-control history via git log, filters commits by the keyword "Evolution," formats them, and saves a markdown report. While use of shell access is consistent with invoking git, the primary purpose is materially different from the declared purpose. This is a clear description-behavior mismatch.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 98% confidence
• Finding: The code is a reporting utility, not a self-evolution engine. It parses `evolution_history_full.md`, groups entries into categories/components, builds a markdown summary, and writes `evolution_human_summary.md`. There is no network or shell use, no agent modification, no decision logic for improvements, and no mechanism to apply constrained evolution. The declared description materially overstates and misrepresents the code’s primary purpose.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 99% confidence
• Finding: The code does not analyze agent runtime history or perform any form of AI self-evolution. Its primary purpose is CI/release engineering for publishing a project publicly. It uses shell and network access consistently with deployment/publishing tasks, but those behaviors are materially different from the declared purpose. Therefore this is a clear description-behavior mismatch.

Tp4

High

• Category: MCP Tool Poisoning
• Confidence: 96% confidence
• Finding: The supplied code does not analyze runtime history, identify improvements, or apply any evolution logic. Its primary purpose is operational recovery: sleep for a configured delay, find an evolver script in the workspace, and restart it as a child Node process. While this may support an evolver system, it is not itself the declared self-evolution engine behavior. The shell and filesystem usage are consistent with a restart utility, but the actual code chunk’s function is materially different from the declared purpose.

Instead, it is a release/versioning utility: it inspects git commit subjects, determines whether to bump major/minor/patch based on conventional commit patterns, reads the current version from package.json, and writes a semver suggestion file. This is a materially different primary purpose from the declared description. While shell access is used for git commands and filesystem access is present, the main mismatch is functional intent, not permissions.

• Finding: The declared description describes a sophisticated AI self-evolution system, but the provided code only validates that specified JavaScript modules can be loaded successfully. It does not analyze runtime history, identify improvements, modify agent behavior, or implement any evolution protocol. While requiring modules may execute their top-level code, the script's primary purpose is clearly module validation, which is materially different from the declared purpose.

• Finding: The code does not implement a self-evolution engine that analyzes runtime history and applies improvements. Instead, it provides helper functions for exchanging and vetting A2A artifacts: parsing JSON inputs, unwrapping messages, marking incoming assets as external candidates with reduced confidence, computing capsule success streaks from stored events, and selecting assets eligible for broadcast. While it touches evolution events, that use is limited to eligibility checks rather than performing evolution or applying changes. It also includes file-reading behavior via fs, which is not suggested by the description. Network/shell permissions are declared but not used here; over-declared permissions alone are not the issue. The primary purpose is materially different from the declared one.

• Finding: The code chunk is not performing runtime-history analysis or applying self-evolution logic. Its primary function is communications infrastructure for an A2A protocol: constructing hello/publish/fetch/report/decision/revoke messages, persisting node IDs and shared secrets, interacting with a remote hub over HTTP, reading/writing JSONL inbox/outbox files, and maintaining heartbeat state including available work and overdue tasks. While this could support a larger evolution system, this chunk itself is materially different from the declared purpose. The declared permissions (network, shell) are not the main issue; network/file behaviors are consistent with infrastructure, but the described purpose is inaccurate for this code.

• Finding: The supplied code chunk is narrowly focused on recording, reading, and summarizing asset call log entries in a file under an evolution directory. It uses local filesystem operations (create directory, append file, read file) and provides simple filtering and aggregation. There is no evidence here of a self-evolution engine, runtime history analysis for improvements, or any mechanism that applies protocol-constrained evolution. While logging could be a supporting component of a larger evolution system, this chunk’s actual primary behavior is asset-call logging and reporting, which is materially different from the declared description.

• Finding: The supplied code chunk does not implement runtime-history analysis, self-improvement logic, or any protocol-constrained evolution behavior. Instead, it is a small asset utility module focused on preview formatting and metadata normalization. While it does not exercise undeclared sensitive capabilities, its primary purpose is materially different from the declared self-evolution engine functionality, so this is a clear description-behavior mismatch.

• Finding: The code is a small bridge/utility module, not a self-evolution engine. Its concrete behaviors are limited to filesystem helpers (ensuring directories exist, writing prompt and JSON metadata artifacts), string clipping, and constructing a JSON-formatted sessions_spawn(...) string. There is no logic for inspecting runtime history, deriving improvements, enforcing evolution protocols, or applying changes to an agent. While declared permissions include network and shell, the code does not use them; over-declared permissions alone are not the issue. The core mismatch is that the described primary purpose is materially different from the actual implementation.

• Finding: The supplied code does not implement any self-evolution engine behavior, runtime history analysis, or protocol-constrained agent evolution. Instead, it provides deterministic object serialization plus SHA-256 hashing and verification for content-addressable asset identifiers. While this could be a supporting utility within a larger system, this code chunk’s primary behavior is asset hashing/integrity, which is materially different from the declared purpose. No network or shell access occurs in the code.

• Finding: The code chunk does not analyze runtime history, propose improvements, or apply any evolution logic. Its primary purpose is to generate and persist a stable device identifier for node identity and environment fingerprinting. It accesses host and container identity sources such as /etc/machine-id, /proc files, hostname, and MAC addresses, and writes the resulting ID to persistent storage. Those behaviors are materially different from the declared self-evolution purpose, so this is a clear description/behavior mismatch.

• Finding: The declared description centers on agent self-evolution based on runtime history and protocol-constrained improvement. The supplied code does not analyze runtime history, identify improvements, or perform any evolution logic. Instead, it gathers environment/device characteristics and produces a stable fingerprint for classification of execution environments. While such metadata collection could support a larger evolution system, this chunk’s primary purpose is environment fingerprinting, which is materially different from the declared behavior and introduces host-identification capabilities not reflected in the description.

• Finding: The code chunk’s primary function is not a self-evolution engine. It does not analyze runtime history for improvements, modify agent behavior, or apply protocol-constrained evolution. Instead, it prepares and submits reviews about reused Hub assets to a remote API, logs outcomes, and maintains a local deduplication file. While this may support a broader evolution workflow, this specific code’s purpose is materially different from the declared description, so it should be flagged as a mismatch.

• Finding: The declared description centers on a self-evolution/improvement engine, but this code chunk does not perform evolution, optimization, or protocol-constrained agent modification. Its primary function is operational telemetry/incident reporting: deciding when recurring failures merit reporting, building a sanitized issue body, and sending it to GitHub over the network. It also stores reporter state on disk and uses GitHub tokens from the environment. While the code is related to an 'evolver' system context, the implemented behavior is materially different from the declared purpose and includes concrete outbound reporting capabilities not described in the declaration.

• Finding: The code does inspect evolution-related context, but its primary function is not to evolve the agent or apply protocol-constrained improvements. Instead, it creates and returns proactive questions for an external Hub bounty system based on detected issues such as recurring errors, capability gaps, stagnation, failure streaks, feature requests, and performance bottlenecks. It also rate-limits and deduplicates these questions and stores state on disk. This is a materially different purpose from a self-evolution engine that identifies and applies improvements.
