CVE-2023-39319
This may cause the template parser to improperly consider script contexts to be terminated early, causing actions to be improperly escaped.
MEDIUM 6.1EPSS 0.92%
Does this matter?
Lower severity and a low EPSS score (0.92%). Track it; it rarely justifies an emergency change on its own.
Description
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.
