SS-2015-004: TreeDropdownField and TreeMultiSelectField XSS

Medium (?)
Versions Affected:
3.1.9 and lower
Versions Fixed:
Release Date:

A cross-site scripting vulnerability has been discovered in the TreeDropdownField and TreeMultiSelectField.

This vulnerability can only be exploited if a user with CMS access has posted malicious or unescaped HTML into any of the dataobjects used as a data source for either of these fields.

This has been resolved by ensuring that all dataobjects used as a data source have their content safely encoded.
