Description

The Bit Form plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'iconUpload' function in all versions up to, and including, 2.13.3. This makes it possible for authenticated attackers, with administrator-level and above permissions, to upload arbitrary files on the affected site's server which may make remote code execution possible.
