⚡ Risks

Base64 decode + execute pattern in: mermaid.min.js critical

Mitigation: Decode and review obfuscated content before use.

Security bypass pattern detected in: mermaid.min.js critical

Mitigation: This skill attempts to disable security features. Do not use.

Code obfuscation detected in: mermaid.min.js medium

Mitigation: Deobfuscate and review code before use.

Prompt injection patterns detected in: mermaid.min.js high

Mitigation: Review SKILL.md for hidden instructions. Do not use with untrusted input.

Resource abuse detected: RESOURCE_ABUSE_LARGE_ALLOCATION high

Mitigation: Limit memory allocation. Process data in chunks

Unauthorized tool use: MCP_SYS_CRITICAL_ACCESS high

Mitigation: Avoid accessing system directories unless absolutely necessary.

Command injection risk: COMMAND_INJECTION_EVAL, COMMAND_INJECTION_USER_INPUT, MCP_SCRIPT_TAGS critical

Mitigation: Avoid eval(), exec(), and compile(). Use safer alternatives like ast.literal_eval()

Social engineering indicators: SOCIAL_ENG_VAGUE_DESCRIPTION low

Mitigation: Provide clear, detailed description of skill functionality
