Recommendation: Plan a near-term fix — a public PoC already exists.

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. Attackers can upload PHP shells through the Products tab custom file field and access them via the upcp-product-file-uploads directory to execute arbitrary code on the server.
