High impact if exploited, but EPSS currently rates exploitation as unlikely (6.89%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The Adning Advertising plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the _ning_upload_image function in versions up to, and including, 1.5.5. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.
