Low-risk findings.
1 low severity finding. Worth noting, but not necessarily harmful.
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
The runtime workflow ingests and reads PostHog-emitted `$csp_violation` event properties (via `execute-sql` over the `events` table) and uses those fields (e.g., `$csp_blocked_url`, `$csp_document_url`, `$csp_effective_directive`) to drive reporting, which constitutes outsider-authored free text coming from clients reporting CSP violations.
