JSON

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.

Notes

Author	Note
mdeslaur	Packages built using golang need to be rebuilt once the vulnerability has been fixed. This CVE entry does not list packages that need rebuilding outside of the main repository or the Ubuntu variants with PPA overlays.
