Overview

This appears to be a real security skill, but it automatically installs agent hooks that inspect prompts and tool calls and retain related data, so users should review it before installing.

Install only if you want this skill to monitor agent prompts and tool calls. Review the postinstall hook changes, database retention, owner bypass, fail-open behavior, and any notification webhook settings before enabling it; avoid running installation with an untrusted OPENCLAW_HOOKS_DIR value.

Vulnerability Patterns

• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Supply Chain: Unpinned Dependencies, External Script Fetching, Obfuscated Code
• Tool Misuse: Tool Parameter Abuse, Chaining Abuse, Unsafe Defaults
• MCP Least Privilege: Underdeclared Capability, Wildcard Permission, Missing Permission Declaration

Findings (18)

Lp3

Medium

• Category: MCP Least Privilege
• Confidence: 87% confidence
• Finding: The skill documentation describes capabilities that involve shell execution, file access, networking, environment/config handling, hooks, and database writes, but no explicit permission declaration is presented. That mismatch can cause users or host systems to underestimate the skill’s access and trust boundary, which is especially risky for a security-focused tool that intercepts prompts and tool calls.

Intent-Code Divergence

Medium

• Confidence: 96% confidence
• Finding: The implementation unconditionally allows owner users, but the documented decision hierarchy states owners should be allowed unless the severity is CRITICAL. In a security enforcement component, this creates a real authorization bypass: any malicious or compromised owner account can evade blocking even for events classified as CRITICAL, undermining the last-line protection promised by the system.

Missing User Warnings

Medium

• Confidence: 98% confidence
• Finding: The CONTRIBUTING guide tells users not to use public issues for security reports, but the only private path is a placeholder email address ('security contact - to be added'). That leaves reporters without a usable disclosure channel, increasing the chance they abandon reporting or disclose details publicly, delaying remediation and potentially exposing users to active exploitation.

Missing User Warnings

Medium

• Confidence: 89% confidence
• Finding: The README advertises analytics, reputation tracking, event storage, logging, and notifications, but does not clearly warn users that prompts, tool-call data, user identifiers, and other potentially sensitive inputs may be collected and retained. In a security skill that intercepts agent activity, this omission can lead to unintentional collection of sensitive data without informed consent or appropriate minimization.

Missing User Warnings

Medium

• Confidence: 94% confidence
• Finding: The installation instructions state that hooks are enabled for automatic protection, which implies interception of user input and tool calls, but they do not prominently warn users about workflow impact or the fact that content may be inspected and logged. Because this skill operates in a sensitive position between users and agent execution, silent or unclear interception increases privacy and operational risk.

Missing User Warnings

Medium

• Confidence: 93% confidence
• Finding: The skill prominently advertises analytics, reputation tracking, event logging, user IDs, session IDs, and a security database, but the high-level description does not clearly warn that user identifiers and behavior will be stored and analyzed. This creates a privacy and transparency issue because operators may deploy it without understanding that it collects potentially sensitive metadata.

Missing User Warnings

Medium

• Confidence: 95% confidence
• Finding: The hook installation section says protection is automatic and transparent, but it does not explicitly warn that user prompts and tool-call parameters will be intercepted and scanned before execution. Transparent interception of all submissions changes the trust model and can expose sensitive content unless users are clearly informed and consent to it.

Missing User Warnings

Medium

• Confidence: 87% confidence
• Finding: The README documents commands for viewing security events by user ID and earlier configuration retains analytics for 365 days, implying potentially long-term storage of user-associated security data. In an AI agent context, those logs may contain sensitive prompts, identifiers, or security-relevant metadata, creating privacy and compliance exposure if users are not clearly informed and retention is not minimized.

Missing User Warnings

Medium

• Confidence: 93% confidence
• Finding: The documentation states that all validations are logged and even supports per-user event queries, but it does not clearly warn users that their prompts and associated identifiers may be retained for audit and analytics. In a security-focused input validation hook, this increases privacy and compliance risk because users may submit sensitive prompts, secrets, or personal data under the assumption that scanning is ephemeral.

Missing User Warnings

Medium

• Confidence: 97% confidence
• Finding: This is a true fail-open condition: any unexpected error during config loading, database initialization, engine setup, or validation causes the hook to log the error and allow the tool call to proceed. In a security gate whose purpose is to block dangerous tool parameters before execution, this means an attacker can potentially bypass protection by triggering validator errors, leaving risky commands, paths, or URLs uninspected.

Missing User Warnings

Medium

• Confidence: 91% confidence
• Finding: This code forwards security event data containing userId, module, fingerprint, message, and timestamps to arbitrary externally configured webhook, Slack, and Discord URLs. Even if this is intended functionality, it creates a real privacy and data-governance risk because potentially sensitive identifiers and incident details can be exfiltrated to third-party services without any minimization, allowlisting, consent, or explicit safety controls in this component.

Natural-Language Policy Violations

Medium

• Confidence: 95% confidence
• Finding: The `unicode_homoglyphs` rule explicitly treats mixed Latin/Cyrillic text as suspicious across `language: 'all'`, and its description/examples frame Cyrillic usage itself as a threat indicator. In a security product, this can create systematic bias against legitimate non-English content, leading to false positives, content blocking, or policy-violating detections for benign multilingual users.

Instruction Override
