A member with only Wiki access to a private repository can submit a markup preview request and retrieve a private pull request's title and state icon despite lacking Issues and Pull Requests access. This exposes pull request metadata across repository unit permissions.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","cwes":["CWE-284"],"vendors":[],"products":[],"references":[{"url":"https://blog.gitea.com/release-of-1.27.3/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39045","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39054","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5w72-2mqm-qh46","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/39045","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39054","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5w72-2mqm-qh46","tags":[]}],"hasPoc":true,"ai":null}
