Percentile
49.0%
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 />
Input:
{ 'foo' : 'test.com onload=alert(1)'}
Rendered result:
<a href />
Recommendation
Update to version 4.0.0 or later.
Alternatively, ensure that all attributes in handlebars templates are encapsulated with quotes.
