NVD Description

Note: Versions mentioned in the description apply only to the upstream php:8.3/php-dba package and not the php:8.3/php-dba package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

In PHP versions 8.2.* before 8.2.31, 8.3.* before 8.3.31, 8.4.* before 8.4.21, 8.5.* before 8.5.6, due to improper sanitation of user data, it allows an attacker to compose an URL, which will cause the target to execute arbitrary JavaScript code (XSS) on the target's machine when the target is viewing the PHP-FPM status page.
