| SOGo before 5.12.11 constructs password-reset links using the
| client-supplied Origin header as the authority, allowing

| 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.
