A signed-in user who could read an issue could therefore add or remove reactions on a locked issue and its comments, bypassing the interaction restriction of the lock. Only reactions were affected; no content could be changed.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","cwes":[],"vendors":[],"products":[],"references":[{"url":"https://blog.gitea.com/release-of-28.2.0/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39839","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39847","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v28.2.0","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-wx44-9m3m-rjqx","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/39839","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39847","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v28.2.0","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-wx44-9m3m-rjqx","tags":[]}],"hasPoc":true,"ai":null}
