📄 Description (English)

Vikunja is an open-source self-hosted task management platform. Versions prior to 2.1.0 have a business logic vulnerability exists in the password reset mechanism of vikunja/api that allows password reset tokens to be reused indefinitely. Due to a failure to invalidate tokens upon use and a critical logic bug in the token cleanup cron job, reset tokens remain valid forever. This allows an attacker who intercepts a single reset token (via logs, browser history, or phishing) to perform a complete, persistent account takeover at any point in the future, bypassing standard authentication controls. Version 2.1.0 contains a patch for the issue.

🤖 AI Executive Summary

Vikunja versions before 2.1.0 contain a critical password reset token vulnerability allowing indefinite reuse of tokens for account takeover. An attacker intercepting a single reset token can permanently compromise user accounts by bypassing authentication controls.
