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.md and companion guide explicitly instruct the agent to open arbitrary public URLs (e.g., "agent-browser open " and examples like https://trendforce.cn, https://prismark.com, news and social sites) and to snapshot/get text/html from those pages, meaning the skill browses and ingests untrusted third‑party web content that can influence subsequent actions.
