Low

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

At runtime, the workflow reads outsider-authored free text from user-provided Zeek conn.log or NetFlow CSV/JSON files passed via `--input` and parses each line into LLM-ingested structured fields (e.g., `parse_zeek_conn_log` / `parse_netflow_csv`).
