Name of the Vulnerable Software and Affected Versions Gitea affected versions not specified Description During repository migration from another Gitea instance, the software uses the page size reported by the source server's API to manage paginated downloads. If a source server reports the max...

CVE-2026-104636: Server-Side Request Forgery (SSRF)

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...

With repository FORCE PRIVATE = true, Gitea creates new repositories as private, but the post-receive hook still applied the repo.private=false push option to an empty repository created by push. Any user who can create repositories could make their new repository public in violation of the...

CVE-2026-70357: Server-Side Request Forgery (SSRF)

Gitea validates a repository migration hostname against its network allow and block lists before invoking Git, but the Git subprocess independently resolves the hostname when connecting. An attacker who can start a migration and control the destination's DNS can change the address between...

When a private repository is transferred to a user who lacks access, Gitea grants that recipient temporary read access as a collaborator so they can review the repository. Rejecting or cancelling the transfer did not revoke this collaboration, so the named recipient kept persistent read access to...

CVE-2026-101029: Generation of Error Message Containing Sensitive Information

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 th...

When a push was authenticated with a deploy key, Gitea recorded the repository owner as the pusher, so permission checks in the push hook pipeline evaluated the owner instead of the deploy key. A holder of a writable deploy key could create protected tags without being on the tag allow list and...
