A fork pull request author can supply a workflow matching a required status context but deliberately prevent it from running. Because skipped statuses count as success, branch protection or organization-required workflow checks can appear satisfied without the mandated workflow executing; no runner or maintainer approval is required for this path.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","cwes":["CWE-284","CWE-345","CWE-693","CWE-807"],"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-5xp7-r6cr-39ff","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-5xp7-r6cr-39ff","tags":[]}],"hasPoc":true,"ai":null}
