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.

Recommendations For versions up to, and including, 4.3.5, update to a version that includes a fix for the insufficient file type validation in the ajaxUploadFonts function. As a temporary workaround, consider disabling the ajaxUploadFonts function until a patch is available.
