NVD Description

Note: Versions mentioned in the description apply only to the upstream sogo package and not the sogo package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

SOGo before 5.12.11 constructs password-reset links using the client-supplied Origin header as the authority, allowing unauthenticated attackers to redirect recovery tokens to attacker-controlled domains. Attackers can submit password recovery requests with a malicious Origin header to have valid password-reset tokens mailed to victim recovery addresses within links pointing to attacker infrastructure, enabling account takeover.
