Improper handling of HTML-like comments in script contexts in html/template
Quick fix
GO-2023-2041 — stdlib: upgrade to the fixed version with the command below.
go get stdlib@v1.20.8Details
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.
