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
Third-party content exposure detected (high risk: 0.80). SKILL.md's "Run React Codemods" section explicitly instructs fetching and running codemod transforms from public URLs (e.g., npx jscodeshift -t https://raw.githubusercontent.com/...) and third‑party codemod packages, which are untrusted public content that the workflow relies on to perform automated code changes and could therefore inject instructions that alter tool actions.
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
Potentially malicious external URL detected (high risk: 1.00). The skill includes commands that run jscodeshift against remote transform scripts hosted on raw.githubusercontent.com (e.g. https://raw.githubusercontent.com/reactjs/react-codemod/master/transforms/rename-unsafe-lifecycles.js), which are fetched and executed at runtime as codemods and therefore constitute externally hosted code that directly executes during the workflow.
