CVE-2023-38877: Economizzer

High severity, CVSS 8.8. EPSS: 1.1% chance of exploitation in the next 30 days.

A host header injection vulnerability exists in gugoan's Economizzer v.0.9-beta1 and commit 3730880 (April 2023). By sending a specially crafted host header in the reset password request, it is possible to send password reset links to users which, once clicked, lead to an attacker-controlled server and thus leak the password reset token. This allows an attacker to reset other users' passwords.
