CVE-2022-4949: Adsanityplugin Adsanity

High severity, CVSS 8.8. EPSS: 2.2% chance of exploitation in the next 30 days.

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.

Affected products

• Xen Xen: affected versions not specified
