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 (medium risk: 0.65). The skill ingests **outsider-authored free text** from Microsoft Graph responses—specifically `log.get("additionalDetails")` and other `targetResources`/rule fields returned by `/auditLogs/directoryAudits` and `/users/{id}/mailFolders/inbox/messageRules`—which are populated from audit log content created by other principals (e.g., attackers/users) and then placed into the agent’s LLM-readable JSON output context.
