2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
The skill's workflows and CI examples explicitly ingest and review code diffs and pull/merge request content from external repositories (e.g., "git diff origin/${{ github.base_ref }}...HEAD > diff.txt" and the GitHub PR comment trigger "@codex review", GitHub/GitLab/Jenkins CI steps that run `codex exec "Review the ... changes"`), which are untrusted, user-generated third-party inputs that the agent reads and acts on (including posting review comments), enabling indirect prompt injection.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The workflow examples fetch and execute external code at runtime — specifically the GitHub Action openai/codex-action@main (https://github.com/openai/codex-action) and the Codex CLI installed via npm (npm install -g @openai/codex, i.e., fetched from the npm registry) — which run remote code that controls the review prompts/execution.
