The collaborator can promote their effective permissions from Admin to Owner and then perform owner-only operations, including transferring the repository to their own account. This bypasses the intended boundary between repository administration and ownership.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-266"],"vendors":[],"products":[],"references":[{"url":"https://blog.gitea.com/release-of-1.27.2/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/38894","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/38895","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-h62v-wmrr-5qjq","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/38894","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/38895","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.2","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-h62v-wmrr-5qjq","tags":[]}],"hasPoc":true,"ai":null}
