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: 0.80). The skill's "Run React Codemods" section explicitly instructs running npx jscodeshift and npx codemod with transforms hosted on raw.githubusercontent.com and other third‑party codemod packages, which fetches and executes public GitHub/third‑party code that the agent will ingest and act on.
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: 0.90). The codemod commands invoke npx jscodeshift with remote transform scripts hosted on raw.githubusercontent.com (e.g., https://raw.githubusercontent.com/reactjs/react-codemod/master/transforms/rename-unsafe-lifecycles.js and similar URLs), which are fetched at runtime and executed as code, so they are runtime external dependencies that execute remote code.
