gh-stack

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

• Third-party content exposure detected (medium risk: 0.30). In references/commands.md, gh stack sync (and view) fetches PRs added to a GitHub stack from github.com and then refreshes PR state, so outsider-authored PR text/comments/body is ingested from the GitHub API at runtime.

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

• Potentially malicious external URL detected (high risk: 0.90). The SKILL.md setup instructs running "gh extension install github/gh-stack", which fetches and installs remote code from the GitHub repository "github/gh-stack" at runtime and thus causes execution of externally fetched code.
