2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
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.
Third-party content exposure detected (high risk: 1.00). The skill explicitly fetches and ingests GitHub PR data (using "gh pr view" and "gh pr diff" on the repository) and requires the agent to read and act on untrusted, user-generated PR content to generate review comments, which could enable indirect prompt injection.
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.
Potentially malicious external URL detected (high risk: 0.80). The skill runs gh commands against the GitHub repo URL (e.g. https://github.com/DataDog/dd-trace-dotnet) at runtime to fetch PR details and diffs which are then injected into the agent’s analysis and used to generate comments, so external content directly controls the agent’s prompts/output.
