Description

The AdSanity plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'ajax_upload' function in versions up to, and including, 1.8.1. This makes it possible for authenticated attackers with Contributor+ level privileges to upload arbitrary files on the affected sites server which makes remote code execution possible.

• xen: all versions

How to fix

Upgrade to a fixed version: Adsanityplugin Adsanity 1.8.2. Check the vendor advisory for mitigations.
