Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.95). The skill uses
bash_tool+curlto fetch outsider-authored free text from the user-supplied domain’s well-known paths (/robots.txt,/llms.txt,/llms-full.txt), thencat/head/wcthose files into the agent’s runtime context for auditing and reporting.
MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).
- Potentially malicious external URL detected (high risk: 0.90). The skill uses bash_tool to fetch and inject remote content at runtime (curl "https://$DOMAIN/robots.txt", "https://$DOMAIN/llms.txt", and "https://$DOMAIN/llms-full.txt" and any custom paths discovered) into the model's context to drive its audit, so those external files can directly influence the agent's prompts/output.
MEDIUM W021: Hidden or invisible Unicode characters detected (potential obfuscation or prompt injection).
- Hidden Unicode characters detected (1 type(s) found)
