Vulnerability from cvelistv5 – Published: 2023-09-08 16:13 – Updated: 2025-02-13 17:02
VLAI?
Summary
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.
Severity ?
No CVSS data available.
