CVE-2026-35597

Vikunja prior to 2.3.0 is vulnerable to TOTP brute-forcing because the login failure path writes the account lock status (StatusAccountLocked) on the same DB session that is rolled back after a failed TOTP check. The in-memory counter in HandleFailedTOTPAuth tracks failures, and once it reaches 1...
