mustache package before 2.2.1 for Node.js allows remote attackers to conduct cross-site scripting (XSS) attacks by leveraging a template with an attribute that is not quoted.

Affected: npm: mustache

Versions of `mustache` prior to 2.2.1 are affected by a cross-site scripting vulnerability when attributes in mustache templates are not quoted.

### Example Template: ```<a href={{foo}}/>```

Input: ```{ 'foo' : 'test.com onload=alert(1)'}```

Rendered result: ```<a href=test.com onload=alert(1)/>```

## Recommendation

Update to version 2.2.1 or later. Alternatively, ensure that all attributes in hmustache templates are encapsulated with quotes.
