NVD Description

Note: Versions mentioned in the description apply only to the upstream falco package and not the falco package as distributed by Wolfi. See How to fix? for Wolfi 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.
