A user with package write access to an owner, for example their own account on an instance with open registration, could repeatedly upload small, highly compressed archives that make the server spend CPU time proportional to the decompressed size, degrading the availability of the Gitea instance. The issue does not allow code execution or data access.","epss":{"date":"2026-11-06","percentile":0.11266,"score":0.0021},"exploits":[],"kev":null,"metrics":[],"modifiedAt":1793980643160,"publishedAt":1793526525233,"references":[{"source":"CNA: Gitea","tags":["vendor-advisory"],"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-r6mh-qg79-rqj2"},{"source":"CNA: Gitea","tags":["patch"],"url":"https://github.com/go-gitea/gitea/pull/39942"},{"source":"CNA: Gitea","tags":["patch"],"url":"https://github.com/go-gitea/gitea/pull/40085"},{"source":"CNA: Gitea","tags":["release-notes"],"url":"https://blog.gitea.com/release-of-28.3.0/"},{"source":"CNA: Gitea","tags":["release-notes"],"url":"https://github.com/go-gitea/gitea/releases/tag/v28.3.0"},{"source":"88ee5874-cf24-4952-aea0-31affedb7ff2","tags":[],"url":"https://blog.gitea.com/release-of-28.3.0/"},{"source":"88ee5874-cf24-4952-aea0-31affedb7ff2","tags":[],"url":"https://github.com/go-gitea/gitea/pull/39942"},{"source":"88ee5874-cf24-4952-aea0-31affedb7ff2","tags":[],"url":"https://github.com/go-gitea/gitea/pull/40085"},{"source":"88ee5874-cf24-4952-aea0-31affedb7ff2","tags":[],"url":"https://github.com/go-gitea/gitea/releases/tag/v28.3.0"},{"source":"88ee5874-cf24-4952-aea0-31affedb7ff2","tags":[],"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-r6mh-qg79-rqj2"},{"source":"GitHub Security Advisories","tags":["advisory"],"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-r6mh-qg79-rqj2"}],"remediation":[{"kind":"fix","source":"CNA: Gitea","text":"The reporting source identifies this reference as a patch.
