Disclosure summary
Vikunja is an open-source self-hosted task management platform. Versions prior to 2.4.0 store password-reset, email-confirmation, and account-deletion tokens in the `user_tokens` table in plaintext. If an attacker gains read access to the database through a backup leak, misconfigured storage, or SQL-level exposure, they can immediately use pending tokens to take over user accounts without knowing passwords. Version 2.4.0 fixes the issue.
