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: 0.95). Outsider-authored free text is ingested when the workflow calls Exa endpoints like `findSimilarAndContents` / `getContents` / `answer`, which fetch and extract readable page text from arbitrary external URLs at runtime (public web content authored by others) and then returns it into the agent/LLM context.
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: 0.90). The skill calls Exa runtime methods that fetch and inject external page content (e.g., exa.getContents([...]) fetching URLs like https://arxiv.org/abs/2401.00001) which are used to generate AI answers/citations, so remote page content can directly influence the agent's prompts/responses.
