Browser Fingerprinting

Security checks for vulnerabilities and agentic risk

Overview

This skill is a static reference helper that prints documentation and does not access credentials, networks, or local data.

Install this as a lightweight documentation skill. Be aware that the guidance appears boilerplate and one cheatsheet command name is inaccurate, so verify any operational migration steps against your own production procedures before acting on them.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs
Vulnerability Patterns

Credential Access

High
Category
Privilege Escalation
Confidence
70% confidence
Finding

Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Missing User Warnings

Medium
Category

Confidence
92% confidence
Finding

This shell skill is a code file that presents migration steps including exporting/importing data, switching traffic live, and decommissioning the old system. Those are potentially irreversible or service-impacting operations, but the script provides no explicit user-facing warning, confirmation prompt, or cautionary note around the risks.

No source excerpt is available for this finding.

Intent-Code Divergence

Low
Category
Not specified by scanner
Confidence
98% confidence
Finding

The cheatsheet says the skill supports a 'troubleshooting' command, but the actual dispatcher only implements 'debugging' and has no 'troubleshooting' case. This is an active documentation/code mismatch that could mislead users about the tool's interface.
