Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
The skill's required workflow (SKILL.md Step 2) explicitly fetches and parses GTFOBins pages from the public site https://gtfobins.org/gtfobins/<command>/ (and fallback offline files in resources/gtfobins/<command>.md), causing the agent to read untrusted, public user-contributed content that directly informs test-generation and decision-making.
