CVE-2026-58422Public exploitNetwork attack vector

Account reactivation via unconditional OAuth callback update

Published Jul 3, 2026 · Updated Jul 3, 2026

Improper authorization in Gitea 1.26.1 and earlier allows remote authenticated users to reactivate disabled accounts through OAuth callbacks. The handleOAuth2SignIn handler treats the local IsActive flag as stale and writes it back as true after a linked identity provider authenticates the user. A linked external identity and an administrator-disabled local account are required; successful exploitation restores a session and the account's repository, organization, and token access.
