SA-CONTRIB-2013-052 - Display Suite - Cross Site Scripting (XSS)

Display Suite allows you to take full control over how your content is displayed using a drag and drop interface.

In certain situations, Display Suite does not properly sanitize entity bundle labels, allowing a malicious user to embed scripts within a page, resulting in a Cross-site Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact that an attacker has to be able to create entity bundle labels of some sort, which usually needs a higher level permission such as administer taxonomy.
