A fork author can modify a referenced reusable workflow so attacker-controlled code executes with the repository and organization secrets available to that event. Exploitation requires a base workflow that calls a local reusable workflow, and bypasses the intended separation between trusted base code and untrusted fork code.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-94","CWE-829"],"vendors":[],"products":[],"references":[{"url":"https://blog.gitea.com/release-of-1.27.2/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/38886","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/38897","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-r9ch-mqjm-g67v","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/38886","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/38897","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-r9ch-mqjm-g67v","tags":[]}],"hasPoc":true,"ai":null}
