| summary: Improper handling of special tags within script contexts in html/template |
| description: |- |
| The html/template package does not apply the proper rules for handling |
| occurrences of "<script", "<!--", and "</script" within JS literals in <script> |
| contexts. This may cause the template parser to improperly consider script |
| contexts to be terminated early, causing actions to be improperly escaped. This |
| could be leveraged to perform an XSS attack. |
