NewCVE-2026-104636 (opens in a new tab)How to fix?
Upgrade Minimos:latest gitea to version 28.0.0-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream gitea package and not the gitea package as distributed by Minimos.
See How to fix? for Minimos:latest relevant fixed versions and status.
Gitea validated the initial remote URL for push mirrors, wiki remote checks, and fetches of migrated pull request heads, but the subsequent raw Git operations followed HTTP redirects without revalidating the destination. A repository administrator using a policy-allowed endpoint that redirects could make Gitea's Git client send requests to an address that the outbound host policy would otherwise block. The impact depends on the configured policy and the internal services reachable from the server.
