Risk Level: CRITICAL
Full Analysis
CRITICAL E005: Suspicious download URL detected in skill instructions.
- Suspicious download URL detected (high risk: 0.80). The set is high-risk: the skill instructs piping a remote shell script (curl | sh) from an untrusted domain (cli.inference.sh/inference.sh) and downloading binaries whose checksums are hosted on the same domain (dist.inference.sh), which makes it trivial for a compromised or malicious domain to distribute malware; the top-result article URLs are likely benign pages but are not the installer source.
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). This SKILL.md explicitly instructs fetching and analyzing top-ranking public URLs (see "SERP Analysis Process" Step 2:
infsh app run tavily/extract --input '{"urls": ["https://top-result-1.com/article", "https://top-result-2.com/article"]}'and related search commands), so the agent ingests untrusted, user-generated/open-web content that directly shapes its decisions and outputs, enabling indirect prompt injection.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill's Quick Start tells users to run a remote installer that is fetched and executed at runtime via "curl -fsSL https://cli.inference.sh | sh" (which then downloads binaries from dist.inference.sh), so this URL chain executes remote code and is required for the infsh commands the skill demonstrates.
