    CVE-2023-39318

    Published: 8 Sept 2023Last Modified: 12 Aug 2026

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

    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.
