Vikunja’s Improper Access Control Enables Bypass of Administrator-Imposed Account Disablement

Assigner: GitHub_M

Vikunja is an open-source self-hosted task management platform. Prior to version 2.2.0, a flaw in Vikunja’s password reset logic allows disabled users to regain access to their accounts. The ResetPassword() function sets the user’s status to StatusActive after a successful password reset without verifying whether the account was previously disabled. By requesting a reset token through /api/v1/user/password/token and completing the reset via /api/v1/user/password/reset, a disabled user can reactivate their account and bypass administrator-imposed account disablement. Version 2.2.0 patches the issue.
