| summary: Improper handling of HTML-like comments in script contexts in html/template |
| description: |- |
| 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. |
