CoreShop Vulnerable to Remote Code Execution (RCE) via Insecure `pull_request_target` Configuration_CVE-2026-41249

{
    "lastseen": "",
    "description": "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.",
