CVE-2023-39318

MEDIUM6.1

Improper handling of HTML-like comments in script contexts in html/template

Published Sep 8, 2023

Modified 11 months ago

No fix available

Details

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.
