| Package | Affected versions | Patched versions |
|---|---|---|
| mustache.js | ≤ 2.2.0 | |
| mustache | < 2.2.1 | 2.2.1 |
Versions of mustache prior to 2.2.1 are affected by a cross-site scripting vulnerability when attributes in mustache templates are not quoted.
Template:
<a href={{foo}}/>
Input:
{ 'foo' : 'test.com onload=alert(1)'}
Rendered result:
<a href=test.com onload=alert(1)/>
Update to version 2.2.1 or later. Alternatively, ensure that all attributes in hmustache templates are encapsulated with quotes.
