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.
Third-party content exposure detected (high risk: 0.80). The skill's middleware and routes (app/middleware/json_parser.rb and app/routes/users.rb) parse and act on arbitrary JSON HTTP request bodies and headers (user-generated, untrusted input) which are used to create/update/delete records and set current user context, so external content can materially influence runtime behavior.
