Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Vikunja (Go package code.vikunja.io/api, versions before 2.4.0) stores password-reset, email-confirmation and account-deletion tokens in plaintext in the database. An attacker who can read the database, for example through a leaked backup, misconfigured storage or SQL injection, can use pending tokens to take over user accounts, including admin accounts, without knowing passwords. Upgrade to version 2.4.0 or later.
