The html/template package does not properly handle HTML-like โ€œโ€ comment tokens, nor hashbang โ€œ#!โ€ 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.
