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: 0.70). The required workflow is to send user-provided documents (e.g., PDFs/images/HTML) to the Nutrient API for text extraction/OCR, which means any free text contained in those outsider-authored documents can be ingested back into the agent’s LLM context via the extracted text/OCR output.
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 MCP server config runs npx to fetch and execute the @nutrient-sdk/dws-mcp-server package at runtime (see https://www.npmjs.com/package/@nutrient-sdk/dws-mcp-server), which causes remote code to be fetched and executed as a required runtime dependency.
