Official description

Espressif Shared GitHub DangerJS is a reusable GitHub Action CI DangerJS workflow for Espressif GitHub projects. Prior to 1.0.1, the action's entrypoint.sh invoked DangerJS from the caller's workspace after copying the fork's checkout into it, creating an untrusted search path for both binary resolution and Node.js module resolution. A fork pull request processed by a pull_request_target workflow could therefore cause fork-supplied code to execute inside the action container in place of the action's own code. This vulnerability is fixed in 1.0.1.
