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

  • Third-party content exposure detected (high risk: 0.90). The skill's SKILL.md explicitly calls for listing and fetching Gmail messages via the gateway (e.g., GET https://gateway.maton.ai/google-mail/gmail/v1/users/me/messages and GET /messages/{messageId}), which causes the agent to ingest arbitrary, user-generated/untrusted email content that could contain instructions affecting subsequent actions (send/modify/trash), so it can enable indirect prompt injection.
