SCA: security update for code.vikunja.io/api (GHSA-fgfv-pv97-6cmj)

high Tenable Cloud Security Plugin ID 440163

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Vikunja is an open-source self-hosted task management platform. Prior to 2.3.0, the TOTP failed-attempt
 lockout mechanism is non-functional due to a database transaction handling bug. When a TOTP validation
 fails, the login handler in pkg/routes/api/v1/login.go calls HandleFailedTOTPAuth and then unconditionally
 rolls back. HandleFailedTOTPAuth in pkg/user/totp.go uses an in-memory counter (key-value store) to track
 failed attempts. When the counter reaches 10, it calls user.SetStatus(s, StatusAccountLocked) on the same
 database session s. Because the login handler always rolls back after a TOTP failure, the
 StatusAccountLocked write is undone. The in-memory counter correctly increments past 10, so the lockout
 code executes on every subsequent attempt, but the database write is rolled back every time. This allows
 unlimited brute-force attempts against TOTP codes. This vulnerability is fixed in 2.3.0. (CVE-2026-35597)

Solution

Update the code.vikunja.io/api library and its related packages to version 2.3.0 or later.
