CVE-2026-60021

Gitea GitLab migration denial of service

Published Oct 14, 2026 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed
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.
