Anyone running a self-hosted Vikunja instance older than 2.7.1 is exposed, because the flaw is in the TOTP enroll and enable endpoints. The attacker first needs a stolen session token, so instances where sessions are tightly protected carry less risk. Instances already on 2.7.1 or later are not affected.
Not affected if version-2.7.1-or-later
Who cares self-hosted, vikunja
vikunja version or the image tag and compare it to 2.7.12.7.1 or laterVikunja before 2.7.1 contains a missing authentication vulnerability that allows attackers holding a stolen session to enroll and enable TOTP without the account password.
