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

The skill’s workflow ingests outsider-authored text from uploaded Office documents at runtime (e.g., parsing the contents of an attacker-provided `.xlsx`/`.xlsm` via `markitdown file.xlsx` or `openpyxl.load_workbook` / `pandas.read_excel`), so arbitrary free text embedded in those files can reach the LLM.
