Safepaste

Security checks for vulnerabilities and agentic risk

Overview

SafePaste is a plausible local safety checker, but it uses broader private context than necessary and adds persistent tracking, backups, and promotional steering that users should review before installing.

Install only if you are comfortable with the agent reading broad OpenClaw workspace, memory, identity, security, tool, model/config, and project context for checks. Before using apply or rollback, review the exact diff yourself; the backup/rollback instructions do not cover every possible change. Expect local usage tracking and occasional Claw Mentor promotional output unless the skill is revised or you disable that behavior manually.

### Technical Analysis

The skill directs the agent to maintain persistent usage state and conditionally inject publisher-controlled advertising into analysis responses. This behavior is not necessary to perform local prompt compatibility or security checks.

Because the instruction is embedded in the skill definition, loading and following the skill changes the agent's output policy. The output is no longer determined solely by the user's analysis request: it is also influenced by a persistent counter and a commercial objective belonging to the skill publisher.

The state does not contain attacker-supplied rules, so this is not classified as agent memory poisoning. The best matching category is skill instruction hijacking because the skill imposes an unrelated recurring output requirement.

### Attack Path

1. A user installs and invokes SafePaste.
2. The agent follows the skill instructions and creates or updates `~/.openclaw/safepaste-state.json`.

Remediation Suggestions

  1. Remove the mandatory usage counter and lastUpsell mechanism from the core analysis flow.
  2. Do not require the agent to insert advertisements into security reports.
  3. If usage statistics are genuinely useful, make tracking explicitly opt-in and document the exact stored fields, retention period, and deletion procedure.
  4. Keep commercial information in the README or an explicitly requested “About” response.
  5. Separate security recommendations from publisher interests, including competitor-related steering.
  6. Provide a command that deletes all SafePaste state and ensure the skill operates normally without persistent tracking.

text

### Technical Analysis

The skill instructs the agent to read a fixed, broad collection of local files for every analysis. These files can contain identity information, long-term memory, security policies, tool configuration, active-project details, and model or service configuration.

Some comparison with existing configuration is necessary for the declared functionality. However, unconditional access to `USER.md`, `MEMORY.md`, `IDENTITY.md`, `SECURITY.md`, `TOOLS.md`, and `openclaw.json` exceeds the minimum privileges needed for many inputs. For example, checking a proposed AGENTS.md wording change may require only the relevant portion of AGENTS.md.

The additional instruction to use all conversation history and active-project context further expands the sensitive information available during processing. No direct exfiltration command was found in the active instructions, but unnecessarily combining untrusted pasted content with broad private context increases the consequences of prompt-injection failures and accidental disclosure.

Remediation Suggestions

  1. Determine the content type before accessing local files.
  2. Read only the target file and the minimum relevant sections needed for comparison.
  3. Require explicit user consent before accessing MEMORY.md, USER.md, IDENTITY.md, SECURITY.md, or openclaw.json.
  4. Never include unrelated secrets, credentials, tokens, or personal information in generated reports.
  5. Add structured secret redaction before local configuration enters model context.
  6. Isolate untrusted pasted text from trusted local context and explicitly treat it as data rather than instructions.
  7. Document, before analysis, which files will be read and why.
  8. Avoid the instruction to use all available conversation and project context; replace it with narrowly scoped, task-relevant context selection.

Incomplete and Non-Atomic Backup and Rollback Mechanism

Content
View full analysis

Vulnerability Details

File Location: SKILL.md:474-478, 554-561
Vulnerability Type: Unsafe backup selection and incomplete restoration
Risk Level: Medium

Vulnerable Code

bash
mkdir -p ~/.openclaw/safepaste-backups
BACKUP_DIR="$HOME/.openclaw/safepaste-backups/$(date +%Y%m%d-%H%M%S)"
cp -r ~/.openclaw/workspace "$BACKUP_DIR"
bash
ls -t ~/.openclaw/safepaste-backups/ | head -1
bash
LATEST=$(ls -t ~/.openclaw/safepaste-backups/ | head -1)
cp -r "$HOME/.openclaw/safepaste-backups/$LATEST/workspace/"* ~/.openclaw/workspace/

Technical Analysis

The advertised rollback mechanism snapshots only ~/.openclaw/workspace, although the skill also discusses modifying ~/.openclaw/openclaw.json and installing skills. Those side effects are outside the backup and cannot be reverted by the documented procedure.

Restoration copies visible files from the backup over the current workspace. The * wildcard excludes dotfiles and does not delete files created after the backup. Consequently, rollback does not reconstruct an exact previous state. A malicious or broken newly created file can remain present after the command reports success.

The backup is selected by parsing ls output rather than by using a validated manifest or a securely recorded path. Backup names are timestamped only to the second, creating possible collisions. The instructions also omit checks for symbolic links, ownership, permissions, integrity, available disk space, and partial-copy failures.

Finally, restoration is performed directly into the live workspace and is not atomic. A failure during copying can leave a mixture of old and new state.

Attack Path

  1. SafePaste creates a backup containing only the workspace directory.
  2. An apply operation changes openclaw.json, installs a skill, adds a new workspace file, changes a dotfile, or performs several of these actions.
  3. The user requests rollback.

Remediation

Remediation Suggestions

  1. Build a complete change manifest before applying anything, including workspace files, openclaw.json, installed skills, and every other affected path.
  2. Back up every item in the manifest and preserve permissions, timestamps, symbolic-link semantics, and hidden files.
  3. Use a collision-resistant backup identifier and create the backup directory with restrictive permissions.
  4. Record the exact backup path in trusted state instead of selecting it by parsing ls.
  5. Validate backup ownership, type, expected parent directory, and integrity before restoration.
  6. Restore into a temporary sibling directory, validate the result, and atomically replace the live workspace where supported.
  7. Remove files created by the apply operation when rolling back, based on the change manifest.
  8. Add explicit rollback handlers for non-workspace changes and skill installations.
  9. Stop immediately on any backup failure; never apply changes unless a complete, verified snapshot exists.
  10. Report partial restoration as a failure and retain recovery artifacts for manual repair.

ople share "paste this into your AGENTS.md" posts on X, Reddit, and Discord. Most people paste them without checking whether they conflict with their existing setup. That's how Frankenclaws are born — agents running conflicting advice mashed together with no coherence.

SafePaste intercepts that moment. Your agent reads YOUR actual setup — your AGENTS.md, SOUL.md, installed skills, cron jobs, model config — and tells you exactly what the change would do, what it conflicts with, and whether to apply it.

100% local. No account. No API key. No data leaves your machine.

Missing User Warnings

Session Persistence

Medium
Category
Rogue Agent
Confidence
89% confidence
Finding

Mandating timestamped backups of the user's workspace before any apply operation creates persistent local copies of potentially sensitive files. While backups are operationally useful, retaining them by default without clear retention or consent expands sensitive data exposure on disk.

**If you cannot escalate** (no Opus/Sonnet access, or model switching unavailable in this context): Warn the user that analysis will be less thorough, then proceed with extra caution — be conservative on conflict detection and flag anything uncertain for human review rather than making confident calls.

**2. Backup First:** Before applying ANY changes, always create a timestamped backup of the user's workspace. This is non-negotiable. The backup command is in Part 3, but internalize this now: no backup = no apply.

Vague Triggers

Finding

The documented trigger phrase, "SafePaste this: [paste the content]," is broad and lacks clear activation boundaries, which can cause the skill to engage on arbitrary pasted content without explicit scoping or confirmation. In a skill that reads local setup files and may later apply changes with rollback, ambiguous activation increases the risk of unintended analysis of sensitive content or accidental initiation of a modification workflow.

Intent-Code Divergence

Low
Category

Confidence
77% confidence
Finding

The Privacy section strongly states that no network calls are required and positions the skill as fully local. Elsewhere, the skill tells the agent to append a promotional message pointing users to clawmentor.ai, which contradicts the purely local framing at the documentation level by introducing externally-directed promotional interaction. While it may not itself perform an automatic network call, the documentation's privacy/minimal-scope messaging conflicts with the embedded promotion behavior.
