Critical (9.1) in arrowjs arrowcms. EPSS 0.6% chance of exploitation in the next 30 days.
A host header injection vulnerability exists in the forgot password functionality of ArrowCMS version 1.0.0. By sending a specially crafted host header in the forgot 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 may allow an attacker to reset other users' passwords.
