CVE-2023-39319
MEDIUM6.1EPSS 0.09%Improper handling of special tags within script contexts in html/template
Published: 9/7/2023Modified: 4/28/2026
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.
