Name of the Vulnerable Software and Affected Versions The Essential Real Estate plugin for WordPress versions up to, and including, 4.3.5

Description The issue is related to arbitrary file uploads due to insufficient file type validation on the ajaxUploadFonts function. This allows authenticated attackers with subscriber-level capabilities or above to upload arbitrary files on the affected site's server, potentially making remote code execution possible.
