AI-suggested

Upgrade Gitea to version 28.4.0 or later, where the vulnerability is fixed by enforcing a 15-minute lockout after five failed TOTP attempts. No other mitigation is required as the fix addresses the issue directly.

Description

Gitea versions prior to 28.4.0 allowed unlimited attempts to guess six-digit TOTP passcodes during sign-in, password reset, and Basic authentication with the X-Gitea-OTP header. This flaw enabled attackers who know an account's password to bypass two-factor authentication by brute forcing the TOTP code. The issue is fixed in version 28.4.0, which now blocks further attempts for 15 minutes after five failed passcode tries.
