CWE-79  (opens in a new tab)

How to fix?

Upgrade RHEL:9 kernel-rt-debug to version 0:5.14.0-284.36.1.rt14.321.el9_2 or higher.
This issue was patched in RHSA-2023:5009.

NVD Description

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

The html/template package does not apply the proper rules for handling occurrences of "<script", "<!--", and "</script" within JS literals in <script> contexts. This may cause the template parser to improperly consider script contexts to be terminated early, causing actions to be improperly escaped. This could be leveraged to perform an XSS attack.
