W011: Third-party content exposure detected (indirect prompt injection risk)

What this means

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.

Why it was flagged

Third-party content exposure detected (high risk: 0.80). The skill fetches and ingests user profile data from public provider endpoints (e.g., googleConfig.userInfoUrl, githubConfig.userInfoUrl and githubConfig.userEmailsUrl in auth/oauth.service.ts and oauth.controller.ts), which are untrusted/user-generated and are directly used to create/link accounts and issue tokens, so those third-party values can materially influence subsequent actions.
