{"id":"CVE-2026-60021","summary":"Gitea GitLab migration denial of service","details":"Gitea's initial GitLab migration version probe uses an HTTP client without a timeout and does not attach the migration task's cancellation context. An authenticated user who can start migrations can target an attacker-controlled server that keeps the response open indefinitely. The request continues after task cancellation and can exhaust the migration worker pool, preventing other migrations from progressing.","aliases":["GHSA-5952-x23q-p23f"],"modified":"2026-10-15T02:47:44.000913518Z","published":"2026-10-14T14:28:46.424Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/60xxx/CVE-2026-60021.json","cna_assigner":"Gitea","cwe_ids":["CWE-400"]},"references":[{"type":"ADVISORY","url":"https://blog.gitea.com/release-of-1.27.3/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/60xxx/CVE-2026-60021.json"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39023"},{"type":"FIX","url":"https://github.com/go-gitea/gitea/pull/39035"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3"},{"type":"ADVISORY","url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5952-x23q-p23f"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-60021"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/go-gitea/gitea","events":[{"introduced":"8df3d6575a3e07d38b264e5c1581e48aa4a02c88"},{"fixed":"146cc3eec57174711eac0e0a0c7b38670c6e3922"}],"database_specific":{"extracted_events":[{"introduced":"1.16.0"},{"fixed":"1.27.3"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.27.2","v1.27.1","v1.27.0","v1.27.0-rc0","v1.28.0-dev","v1.27.0-dev","v1.26.0-dev","v1.25.0-dev","v1.24.0-dev","v1.22.0-rc1","v1.23.0-dev","v1.22.0-rc0","v1.21.0-rc0","v1.22.0-dev","v1.20.0-rc0","v1.21.0-dev","v1.20.0-dev","v1.19.0-rc0","v1.18.0-rc0","v1.19.0-dev","v1.18.0-dev","v1.17.0-dev","v1.16.0-rc1","v1.16.0-dev"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-60021.json"}}],"schema_version":"1.9.0"}
