How to fix?

There is no fixed version for Centos:9 osbuild-composer-core.

NVD Description

Note: Versions mentioned in the description apply only to the upstream osbuild-composer-core package and not the osbuild-composer-core package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

The html/template package does not properly handle HTML-like "" comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. This may cause the template parser to improperly interpret the contents of <script> contexts, causing actions to be improperly escaped. This may be leveraged to perform an XSS attack.
