How to fix?

Upgrade SLES:15.0 php7-readline to version 7.2.34-150000.4.103.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php7-readline package and not the php7-readline package as distributed by SLES. See How to fix? for SLES:15.0 relevant fixed versions and status.

In PHP versions 7.2.x below 7.2.29, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using get_headers() with user-supplied URL, if the URL contains zero (\0) character, the URL will be silently truncated at it. This may cause some software to make incorrect assumptions about the target of the get_headers() and possibly send some information to a wrong server.
