Full Analysis
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.80). The skill performs DNS lookups of user-supplied domains (check_dns_record in scripts/main.py uses dns.resolver.resolve to fetch public MX/TXT records such as SPF/DKIM/DMARC), which are untrusted, third-party data that the agent parses and displays as part of its workflow.
