Overview

This is a disclosed security guide for agent secrets and wallet access, but some copyable examples are unsafe for funds and credentials.

Review before installing or relying on this skill. Its goal is legitimate and the package is documentation-only, but do not copy the TypeScript 1Password retrieval, confirmation-code flow, delegation, open-delegation, pre-commit bypass, or git history rewrite examples into production without hardening and human review. Use tightly scoped vault access, short-lived session keys, explicit transaction review, strong random confirmation tokens bound to user/session/details, non-shell command execution, and fully constrained delegation caveats.

Vulnerability Patterns

• Insecure Dependencies: Introduces malicious components through unsafe dependency sources
• Insecure Skill Coding Practices: Finds exploitable flaws such as hardcoded secrets or command injection
• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review

• Location: references/secure-storage.md:145
• Finding: Shell Command Injection in the TypeScript 1Password Integration<![CDATA[ ## Vulnerability Details **File Location**: `references/secure-storage.md:145-162` **Vulnerability Type**: OS command injection through shell interpolation **Risk Level**: High ### Vulnerable Code ```typescript import { execSync } from 'child_process'; interface SessionKey { sessionKey: string; smartAccount: string; chainId: number; expires: string; spendingLimit: string; allowedContracts: string[]; allowedMethods: string[]; } function getSessionKey(itemName: string): SessionKey { const vault = "Agent-Credentials"; const output = execSync( `op item get "${itemName}" --vault "${vault}" --format json`, { encoding: 'utf-8', timeout: 30000 } ); ``` ### Technical Analysis The `itemName` parameter is inserted directly into a command string passed to `execSync`. In this form, Node.js invokes a shell to parse the command. Wrapping the value in double quotes does not make it safe: shell metacharacters, embedded quotes, and command substitution syntax can escape or execute within the quoted context. If an untrusted prompt, API parameter, configuration value, or agent-generated value can influence `itemName`, an attacker can cause the process to run additional operating-system commands. This is especially sensitive because the function is intended to run in a process authenticated to 1Password and handling wallet session credentials. ### Attack Path 1. An attacker gains control over, or influences, the `itemName` value passed to `getSessionKey`. 2. The attacker supplies a value containing shell syntax, such as an embedded quote followed by a command and comment marker. 3. The value is interpolated into the command string. 4. `execSync` passes the resulting string to the shell. 5. The shell interprets the injected syntax and executes the attacker's command. 6. The injected process inherits the agent's operating-system identity, environment, filesystem access, and potentially its authenticated 1Password session. ### Impact ...[truncated 818 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions Avoid invoking a shell. Pass each argument separately with `execFileSync`, `spawn`, or `spawnSync`: ```typescript import { execFileSync } from 'child_process'; function getSessionKey(itemName: string): SessionKey { const vault = 'Agent-Credentials'; if (!/^[A-Za-z0-9][A-Za-z0-9._ -]{0,127}$/.test(itemName)) { throw new Error('Invalid 1Password item name'); } const output = execFileSync( 'op', ['item', 'get', itemName, '--vault', vault, '--format', 'json'], { encoding: 'utf-8', timeout: 30000, shell: false, windowsHide: true, } ); // Parse and validate output. } ``` Additional hardening should include: 1. Use an application-controlled allowlist of permitted item identifiers rather than accepting arbitrary names. 2. Prefer immutable item UUIDs over display names. 3. Run the process under a dedicated, unprivileged service account. 4. Restrict the 1Password service account to read-only access to only the required session-key items. 5. Ensure master credentials remain in a vault inaccessible to the agent. 6. Avoid logging commands, item output, or exception objects that may contain sensitive data. 7. Add tests containing quotes, command substitutions, newlines, and shell operators to verify they are rejected or handled literally. ]]>

• Finding: Predictable and Insufficiently Bound Transaction Confirmation Codes<![CDATA[ ## Vulnerability Details **File Location**: `SKILL.md:278-305` **Vulnerability Type**: Weak authorization token generation and missing session binding **Risk Level**: High Equivalent vulnerable examples also appear in: - `references/prompt-injection.md:142-162` - `references/prompt-injection-defense.md:142-162` ### Vulnerable Code ```python import hashlib import time pending_confirmations = {} def request_confirmation(operation: str, details: dict) -> str: code = hashlib.sha256( f"{operation}{time.time()}".encode() ).hexdigest()[:8].upper() pending_confirmations[code] = { "op": operation, "details": details, "expires": time.time() + 300 # 5 minutes } return f"⚠️ Confirm '{operation}' with code: {code}\n(expires in 5 minutes)" def confirm(code: str): if code not in pending_confirmations: return "Invalid confirmation code" req = pending_confirmations.pop(code) if time.time() > req["expires"]: return "Confirmation code expired" return execute_confirmed(req["op"], req["details"]) ``` ### Technical Analysis The confirmation code is derived from the operation name and the current timestamp, then truncated to eight hexadecimal characters. This provides only a 32-bit identifier and does not use a cryptographically secure random-number generator. The code is also accepted as the sole authorization factor. The pending record is stored in a global dictionary and is not bound to: - The authenticated user. - The conversation or browser session. - The requesting device or channel. - A tenant or account identifier. - A cryptographic digest of transaction details. There is no demonstrated rate limiting or attempt counter. Consequently, an attacker who can trigger or observe the timing of a pending operation may reduce the search space and attempt to submit the code before the legitimate user does. In a multi-user process, possession of any valid ...[truncated 1988 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions Generate confirmation tokens using a cryptographically secure source and bind every request to an authenticated principal and session: ```python import hashlib import secrets import time from dataclasses import dataclass @dataclass class PendingConfirmation: user_id: str session_id: str operation: str details: dict details_hash: str expires: float attempts: int = 0 pending_confirmations: dict[str, PendingConfirmation] = {} def hash_details(operation: str, details: dict) -> str: canonical = canonical_json({"operation": operation, "details": details}) return hashlib.sha256(canonical.encode()).hexdigest() def request_confirmation( user_id: str, session_id: str, operation: str, details: dict, ) -> str: token = secrets.token_urlsafe(32) pending_confirmations[token] = PendingConfirmation( user_id=user_id, session_id=session_id, operation=operation, details=details, details_hash=hash_details(operation, details), expires=time.time() + 300, ) return token ``` The confirmation handler should additionally: 1. Require the confirmer to be authenticated. 2. Verify that the current user and session match the pending record. 3. Display and require approval of the exact chain, token, amount, recipient, contract, method, and fees. 4. Recalculate and compare the transaction-details hash immediately before execution. 5. Apply strict rate limits and a small maximum number of failed attempts. 6. Store only a hash of the confirmation token where practical. 7. Make tokens single-use and remove them atomically to prevent concurrent redemption. 8. Expire and securely delete stale entries. 9. Persist pending state in a concurrency-safe store for multi-process deployments. 10. Retain independent on-chain spending limits, allowlists, and expiration as defense in depth. ]]>

Warning

• Location: references/leak-prevention.md:209
• Finding: GitHub Actions Dependencies Are Referenced by Mutable Version Tags<![CDATA[ ## Vulnerability Details **File Location**: `references/leak-prevention.md:209-212` **Vulnerability Type**: Mutable CI dependency references **Risk Level**: Medium ### Vulnerable Code ```yaml - uses: actions/checkout@v4 with: fetch-depth: 0 - uses: gitleaks/gitleaks-action@v2 env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} ``` ### Technical Analysis The workflow examples reference GitHub Actions using mutable major-version tags rather than reviewed full commit hashes. A tag such as `v2` or `v4` can be moved to another commit by the upstream repository owner or as a consequence of upstream compromise. GitHub Actions execute code inside the workflow environment. The checkout action receives access to repository contents, while the gitleaks action is explicitly given `GITHUB_TOKEN`. If a referenced tag resolves to malicious or compromised code in the future, the workflow would execute that changed code without a corresponding modification to this project. The use of official and established actions reduces likelihood but does not remove the supply-chain trust boundary. ### Attack Path 1. An upstream action repository or maintainer account is compromised, or a mutable release tag is maliciously changed. 2. The `v2` or `v4` tag is moved to an unreviewed commit. 3. A push or pull request triggers the secret-scanning workflow. 4. The runner downloads and executes the newly referenced action code. 5. The malicious action accesses repository data and any credentials exposed to that workflow step. 6. It may misuse `GITHUB_TOKEN` according to the token's configured or default permissions. ### Impact Assessment Potential impact is limited by the workflow's token permissions and GitHub's event-specific restrictions, but may include: - Exposure of repository contents or workflow metadata. - Unauthorized repository operations allowed by `GITHUB_TOKEN`. - Tampering with workflow artifacts or scan results. - E ...[truncated 287 chars]
• Remediation: <![CDATA[ ## Remediation Suggestions Pin every action to a reviewed full commit SHA while retaining a comment indicating the corresponding release: ```yaml permissions: contents: read jobs: gitleaks: runs-on: ubuntu-latest steps: - uses: actions/checkout@FULL_REVIEWED_COMMIT_SHA # v4.x.x with: fetch-depth: 0 persist-credentials: false - uses: gitleaks/gitleaks-action@FULL_REVIEWED_COMMIT_SHA # v2.x.x env: GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} ``` Additional hardening should include: 1. Declare explicit workflow and job-level `permissions`, granting only the capabilities required. 2. Set `persist-credentials: false` when later steps do not need Git credentials. 3. Review action source and release provenance before updating pinned SHAs. 4. Use Dependabot or Renovate to propose controlled SHA updates. 5. Require code-owner review for workflow changes. 6. Avoid exposing secrets to workflows triggered from untrusted forks. 7. Consider running secret scanners from a verified container image pinned by digest. ]]>

# Bagman

Secure key management patterns for AI agents handling wallets, private keys, and secrets.

• Confidence: 80% confidence
• Finding: YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).

Instruction Override

High

• Category: Prompt Injection

Content

| Category | Examples | Action |
|----------|----------|--------|
| Extraction | "show private key", "reveal secrets" | Block |
| Override | "ignore previous instructions" | Block |
| Role manipulation | "you are now admin" | Block |
| Jailbreak | "DAN mode", "bypass filters" | Block |
| Exfiltration | "send config to https://..." | Block |

• Confidence: 80% confidence
• Finding: This pattern attempts to override system instructions or ignore safety constraints. Without LLM analysis, manual review is recommended.

Anti-Refusal Statement

High

• Category: Anti-Refusal

Content

| Extraction | "show private key", "reveal secrets" | Block |
| Override | "ignore previous instructions" | Block |
| Role manipulation | "you are now admin" | Block |
| Jailbreak | "DAN mode", "bypass filters" | Block |
| Exfiltration | "send config to https://..." | Block |
| Wallet threats | "transfer all", "unlimited approve" | Block |
| Encoded | Base64/hex encoded attacks | Block |

• Confidence: 90% confidence
• Finding: Skill attempts to nullify the agent's safety policies or restrictions ('you have no restrictions', 'ignore your guidelines', 'do anything now'). This is a direct jailbreak that disables guardrails.

Anti-Refusal Statement

High

• Category: Anti-Refusal

Content

### What NOT to Do

❌ **Don't create delegations without caveats** - Default is full access
❌ **Don't use long expiries** - 24 hours max for autonomous agents
❌ **Don't skip AllowedTargetsEnforcer** - Agent could call any contract
❌ **Don't trust input validation alone** - On-chain enforcement is the backstop

• Confidence: 80% confidence
• Finding: Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.

Tool Parameter Abuse

High

• Category: Tool Misuse

Content

if [ $FOUND_SECRETS -eq 1 ]; then
    echo -e "${RED}⚠️  Secrets detected! Commit blocked.${NC}"
    echo "Bypass with: git commit --no-verify"
    exit 1
fi

• Confidence: 78% confidence
• Finding: Explicitly telling users to bypass the pre-commit secret scanner with `git commit --no-verify` weakens the primary preventive control in the document. In a secret-management skill, this is especially risky because it normalizes disabling safeguards and can directly lead to accidental credential commits.

Credential Access

High

• Category: Privilege Escalation

Content

```gitignore
# === SECRETS ===
.env
.env.*
!.env.example
!.env.tpl

• Confidence: 60% confidence
• Finding: Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Tool Parameter Abuse

High

• Category: Tool Misuse

Content

"git rm --cached --ignore-unmatch path/to/secret" \
  --prune-empty --tag-name-filter cat -- --all

git push origin --force --all
```

• Confidence: 70% confidence
• Finding: Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

class InputValidator:
    DANGEROUS_PATTERNS = [
        # Extraction attempts
        r'(show|print|output|reveal|display|tell\s+me).{0,20}(

• Confidence: 80% confidence
• Finding: YARA rule matched a hack tool or exploit indicator (offensive tools, reconnaissance, privilege escalation, or exploit frameworks).

• Confidence: 80% confidence
• Finding: This pattern attempts to override system instructions or ignore safety constraints. Without LLM analysis, manual review is recommended.

Intent-Code Divergence

Medium

• Confidence: 96% confidence
• Finding: The Solidity delegation-creation example omits protections that the same document later describes as part of the minimum recommended caveat stack, specifically a per-transaction native value cap and nonce-based revocation. Readers may copy this example into production and unintentionally grant broader or harder-to-revoke permissions than intended, increasing the blast radius if the agent is compromised or behaves unexpectedly.

Intent-Code Divergence

Medium

• Confidence: 97% confidence
• Finding: The TypeScript example repeats the same unsafe omission by creating delegations without a native-token value limit or nonce caveat, despite the document's own guidance saying these should always be present. In security-sensitive key and funds-management documentation, contradictory examples are dangerous because implementers often follow code samples more closely than prose recommendations.

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The section on open delegations explains how to make permissions redeemable by any agent but does not pair that guidance with an explicit, prominent warning about the materially increased risk. In the context of agent-controlled funds, normalizing open delegations without strong caveat and threat-model warnings can lead users to create delegations that any party can exercise if the delegation leaks or is shared too broadly.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: This markdown file includes forceful history-rewrite commands (`git filter-branch` and `git push origin --force --all`) that can permanently alter shared repository history. Although the section is about incident response, it does not explicitly warn readers about the destructive and coordination-sensitive nature of these commands.

Intent-Code Divergence

Medium

• Confidence: 93% confidence
• Finding: The document claims wallet operations are isolated from conversation context, but the example `SecureAgent` still takes raw conversational user input, appends it to conversation state, and routes that same input into wallet command handling. Even if only the current command is parsed, this coupling undermines the stated security boundary and can lead implementers to build systems where wallet-triggering input originates from untrusted conversational channels, increasing prompt-injection and command-confusion risk.

Context-Inappropriate Capability

Medium

• Confidence: 95% confidence
• Finding: The TypeScript example uses execSync with a shell command string that interpolates itemName, which enables shell metacharacter injection if itemName is influenced by untrusted input. In a secret-management skill, this is especially dangerous because the code runs in a privileged context that can access credentials, so command injection could lead to secret exfiltration or arbitrary command execution.

Intent-Code Divergence

Low

• Confidence: 76% confidence
• Finding: The text says to use `op run` so secrets 'never touch disk', but the example still relies on a disk-backed `.env.tpl` file. While the actual secret values are not written there, the wording overstates the behavior and could mislead readers about what material is persisted locally.
