CVE-2026-41249

Summary

CoreShop is a Pimcore enhanced eCommerce solution. In versions 5.0.1 through 5.1.0-beta.1,, the GitHub Actions workflow (.github/workflows/static.yml) uses the pull_request_target trigger but dangerously checks out the unverified code from the pull request head (ref: ${{ github.event.pull_request.head.ref }}). Subsequently, it executes a script (bin/console) from this untrusted checkout. This allows any external attacker to achieve Remote Code Execution (RCE) on the GitHub Actions runner simply by submitting a malicious Pull Request. Also known as a "Pwn Request" vulnerability. As of time of publication, pull_request_target is still in the file.
