{"identifier":"CVE-2026-60021","cve":{"id":"CVE-2026-60021","description":"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.","published":"2026-10-14T15:17:21.120000+00:00","modified":"2026-10-18T14:16:55.100000+00:00","status":"Deferred","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","cvss_version":"3.1","affected":[],"weaknesses":["CWE-400"],"references":[{"url":"https://blog.gitea.com/release-of-1.27.3/","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"},{"url":"https://github.com/go-gitea/gitea/pull/39023","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"},{"url":"https://github.com/go-gitea/gitea/pull/39035","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"},{"url":"https://github.com/go-gitea/gitea/releases/tag/v1.27.3","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"},{"url":"https://github.com/go-gitea/gitea/security/advisories/GHSA-5952-x23q-p23f","source":"88ee5874-cf24-4952-aea0-31affedb7ff2"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":6.5,"baseSeverity":"MEDIUM","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":3.6}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-10-18T13:30:24.038745Z","id":"CVE-2026-60021","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:22:15.394684+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00548,"percentile":0.45836,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"blog.gitea.com","source_url":"https://blog.gitea.com/release-of-1.27.3/","investigate_url":"https://investigate.aeglixmind.com/#blog.gitea.com"},{"domain":"github.com","source_url":"https://github.com/go-gitea/gitea/pull/39023","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-60021","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-60021","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-60021","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
