Affected versions of dojo are susceptible to a cross-site scripting vulnerability in the dijit.Editor and textarea components, which execute their contents as Javascript, even when sanitized.

Recommendation

Update to version 1.1.0 or later.

The default configuration of the build process in Dojo 0.4.x before 0.4.4, 1.0.x before 1.0.3, 1.1.x before 1.1.2, 1.2.x before 1.2.4, 1.3.x before 1.3.3, and 1.4.x before 1.4.2 has the copyTests=true and mini=false options, which makes it easier for remote attackers to have an unspecified impact via a request to a (1) test or (2) demo component.
