{"id":"CVE-2026-73273","published":"2026-10-14T15:17:23.410","lastModified":"2026-10-14T16:17:53.353","description":"Gitea's Maven upload handler reads checksum uploads entirely into memory and returns before enforcing package-size quotas. An authenticated user with package-publish permission can submit an oversized body to a checksum endpoint despite legitimate checksum values being at most 128 bytes. This bypasses the upload quota on that path and can exhaust server memory.","cvssScore":4.3,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","cwes":["CWE-770"],"vendors":[],"products":[],"references":[{"url":"https://blog.gitea.com/release-of-1.27.3/","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39028","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39031","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5xcq-p92v-43rf","tags":[]}],"exploitRefs":[{"url":"https://github.com/go-gitea/gitea/pull/39028","tags":[]},{"url":"https://github.com/go-gitea/gitea/pull/39031","tags":[]},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","tags":[]},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5xcq-p92v-43rf","tags":[]}],"hasPoc":true,"ai":null}
