Risk Level: HIGH
Full Analysis
HIGH W007: Insecure credential handling detected in skill instructions.
- Insecure credential handling detected (high risk: 0.90). The prompt includes commands that embed plaintext secrets (e.g., fill @e2 "password123", set credentials user pass, set headers '{"X-Key":"v"}' and saving/loading auth.json), so an agent following it would likely need to output secret values verbatim, creating exfiltration risk.
MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).
- Third-party content exposure detected (high risk: 0.90). The skill explicitly lets the agent navigate to arbitrary public URLs via "agent-browser open " and then snapshot or retrieve page content (e.g., "agent-browser snapshot", "agent-browser get text @e1", "agent-browser get html @e1"), which means it ingests untrusted, user-generated third-party web content that could contain indirect prompt-injection payloads.
