Security patches

Cross site scripting (XSS) was possible due to improper escaping of certain entry editing screen fields and comment input fields.

Custom field patch must be applied after upgrade

After previewing an entry or page that contains image custom fields and then returning to edit the entry or page, the image data becomes corrupted. A patch for this issue was subsequently released May 8, 2014. Please download the version that corresponds to your version of Movable Type:

Install the patch by extracting the archive contents on top of the Movable Type installation folder, resulting in addons/Commercial.pack/lib/CustomFields/ getting replaced with the patched version.
