Vulnerability Title
EDD Product Catalog Feed by PixelYourSite <= 1.0.2 - Authenticated (Subscriber+) Arbitrary Options Deletion via Missing Authorization on 'delete' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The EDD Product Catalog Feed by PixelYourSite plugin for WordPress is vulnerable to unauthorized modification of data that can lead to a denial of service due to a missing capability check on the wpeddpcf_delete_feed function in all versions up to, and including, 1.0.2. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary option values on the WordPress site. This can be leveraged to delete an option that would create an error on the site and deny service to legitimate users.
