Description

WordPress Ultimate Product Catalog 3.8.6 contains an arbitrary file upload vulnerability that allows authenticated users with contributor, editor, author, or administrator roles to upload malicious files by exploiting the custom fields functionality.

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.
