CVE-2026-93031Network attack vector

Code execution via unchecked media import

Published Sep 18, 2026 · Updated Sep 18, 2026

Arbitrary file upload in four WP Cloud Plugins products 2.0 through 3.8.3 allows remote authenticated users to execute server code. The download_file_to_uploads function writes imported files into the WordPress uploads directory without checking their extension or contents against get_allowed_mime_types(), while can_import() lacks a capability check. Subscriber-level access is sufficient; unauthenticated reachability requires specific shortcode parameters on a public module, and execution depends on the server treating the uploaded file as executable.
