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 skill ingests network captures that may contain arbitrary public web content (SKILL.md Step 5: "URLs accessed via HTTP/HTTPS", and scripts/agent.py's extract_http_objects which uses "tshark --export-objects" to extract HTTP objects from PCAPs), and those extracted untrusted third‑party artifacts (URLs, HTTP objects, certificates, user‑agents) are parsed and used to identify C2/exfiltration and drive analysis decisions, so external content can materially influence the agent's actions.
