📛 CVE Title
Vikunja before 2.7.1 Auth Token Leak via API URL Change
Description
Vikunja before 2.7.1 contains a credential exposure vulnerability that allows attackers to steal stored auth tokens by inducing users to switch the frontend API URL. Because checkAndSetApiUrl leaves origin-independent localStorage tokens in place, the bearer token and desktop OAuth refresh token are sent to the attacker's server, enabling account takeover.
