CVE-2026-101029

Gitea migration and pull mirror SSRF through multi-answer DNS

Published Oct 6, 2026 CVSS 3.1 · 4.3 Medium EPSS < 1% KEV · Not listed
Description
Gitea's repository migration and pull mirror egress checks could be bypassed with a hostname that returns multiple DNS answers, because the address that was validated was not necessarily the address Git later connected to. A low-privileged user who can create migrations or mirrors could direct the server to internal services, reading from and writing to reachable internal Git or HTTP endpoints. Content from internal responses could additionally be disclosed through migration and mirror error messages.
