CVE-2026-123002
Gitea missing attempt limit for TOTP passcodes
Description
Gitea accepted an unlimited number of wrong TOTP passcodes during sign-in, in the password reset flow and for Basic authentication with the `X-Gitea-OTP` header. An attacker who already knows an account's password could guess the six-digit passcode by trying codes at a high rate and sign in despite two-factor authentication. After five failed passcodes, further attempts for the account are now refused for 15 minutes.
