MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

• Third-party content exposure detected (low risk: 0.10). The workflow scrapes arbitrary web pages and listings via browser automation where the agent actively searches or fetches user-supplied URLs.

MEDIUM W012: Unverifiable external dependency detected (runtime URL that controls agent).

• Potentially malicious external URL detected (high risk: 0.70). The skill instructs the agent to automatically download and install a runtime dependency from an arbitrary third-party GitHub repository (https://github.com/browser-act/skills/tree/main), introducing an unverified external operational dependency with weak provenance.
