How to fix?

There is no fixed version for Echo:latest golang-1.19.

NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-1.19 package and not the golang-1.19 package as distributed by Echo. See How to fix? for Echo:latest 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.
