Starting in version 4.0.0` and prior to version 4.4.1, this action uses the `github.head_ref` parameter in an insecure way. This vulnerability can be triggered by any user on GitHub on any workflow using the action on pull requests. They just need to create a pull request with a branch name, which can contain the attack payload. This can be used to execute code on the GitHub runners and to exfiltrate any secrets one uses in the CI pipeline. A patched action is available in version 4.4.1. No workaround is available."}], "lastModified": "2023-03-17T16:05:39.477", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:github-slug-action_project:github-slug-action:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "3A0A3629-2003-4230-8082-FD1FB2E171BF", "versionEndExcluding": "4.4.1", "versionStartIncluding": "4.0.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
