Risk Level: MEDIUM
Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). The skill instructs the agent to fetch and parse public, community-maintained Wycheproof test vectors from GitHub/raw.githubusercontent.com (e.g., "git submodule add https://github.com/C2SP/wycheproof.git" and the curl script downloading from https://raw.githubusercontent.com/C2SP/wycheproof/master/testvectors_v1/), so it ingests untrusted third‑party content as part of its workflow.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.80). The included fetch-script performs runtime curl requests to raw GitHub URLs (e.g. https://raw.githubusercontent.com/C2SP/wycheproof/master/testvectors_v1/) to download JSON test vectors that the test harness requires and which directly drive test behavior, so the external content controls runtime behavior.
