2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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
Third-party content exposure detected (high risk: 0.90). The SKILL.md (see "Exa AI-Powered Web Search" description and Step 3: Execute Search / get-contents using tools/exa_search.py with the exa-py SDK) explicitly performs broad web searches and extracts content from arbitrary public URLs (blogs, docs, news, personal sites), and that extracted untrusted content is read and used to present results and drive follow-up actions, so it could enable indirect prompt injection.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.80). The skill explicitly runs the helper to fetch arbitrary external pages at runtime (e.g., python3 "$SCRIPT" get-contents "URL1" "URL2" --content text), and that fetched page content is injected into the agent/LLM flow for extraction and summarization, meaning user-supplied remote URLs can directly control prompts and outputs.
