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 required workflow reads and treats extension-owned files like `qwen-extension.json`, `QWEN.md`, `commands/*.md`, `skills/*/SKILL.md`, and `agent markdown` as “untrusted” and model-facing content before customizing, meaning outsider-authored text from a user-provided or pre-existing extension directory can be ingested into the agent/LLM context (even if the doc says not to follow instructions inside it).
