An approved fork workflow targeting a private repository can read workflow files from another private repository that trusts the base repository's owner through collaborative-owner configuration. The issue exposes private reusable workflow contents at caller-selected Git refs; it does not itself grant write access or code execution in the other repository.","cvssScore":5.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","cwes":["CWE-280"],"vendors":[],"products":[],"references":[{"url":"https://blog.gitea.com/release-of-1.27.3/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39005","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39018","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-2xph-7j4g-43rg","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/39005","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39018","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-2xph-7j4g-43rg","tags":[]}],"hasPoc":true,"ai":null}
