The handlebars package before 4.0.0 for Node.js allows remote attackers to conduct cross-site scripting (XSS) attacks by leveraging a template with an attribute that is not quoted.

GHSA-9prh-257w-9277 — Cross-Site Scripting in handlebars

Affected: npm: handlebars

Versions of `handlebars` prior to 4.0.0 are affected by a cross-site scripting vulnerability when attributes in handlebar templates are not quoted.

## Proof of Concept Template: ```<a href={{foo}}/>```

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

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

## Recommendation

Update to version 4.0.0 or later. Alternatively, ensure that all attributes in handlebars templates are encapsulated with quotes.
