Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.60%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

PILOS is an open source front-end for BigBlueButton servers with a built-in load balancer. The password reset component deployed within PILOS uses the hostname supplied within the request host header when building a password reset URL. It may be possible to manipulate the URL sent to PILOS users when so that it points to the attackers server thereby disclosing the password reset token if/when the link is followed. This only affects local user accounts and requires the password reset option to be enabled. This issue has been patched in version 2.3.0.
