How to fix?

Upgrade SLES:15.2 php7-ctype to version 7.4.33-150200.3.46.2 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php7-ctype package and not the php7-ctype package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

In PHP versions 7.3.x below 7.3.26, 7.4.x below 7.4.14 and 8.0.0, when validating URL with functions like filter_var($url, FILTER_VALIDATE_URL), PHP will accept an URL with invalid password as valid URL. This may lead to functions that rely on URL being valid to mis-parse the URL and produce wrong data as components of the URL.
