No fix is confirmed yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for the fix.

Improper handling of the returnUrl parameter in the Forgot Password function of Veeam Service Provider Console allows an unauthenticated attacker to control the domain of the generated password reset link. When the targeted user clicks the link delivered by email, the reset code is transmitted to an attacker-controlled host, allowing the attacker to take over the account.
