CVE-2026-53683: Red Hat Enterprise Linux 10

Medium severity, CVSS 4.3. EPSS: 0.3% chance of exploitation in the next 30 days.

reset_password.html parses query string parameters and uses the 'url' parameter as a redirection target (window.location = url) after password reset, optionally delayed by a 'delay' parameter. No validation or allowlisting is performed on url, enabling an attacker to redirect users to an arbitrary external site after completion of the password-reset workflow.
