CVE-2026-16601Network attack vector

Subscriber-level code execution via incomplete upload filtering

Published Aug 25, 2026 · Updated Aug 27, 2026

Arbitrary file upload in CreativeMinds CM Map Locations 2.1.8 and earlier allows remote authenticated users to execute server-side code. The uploadMedia handler incompletely filters filename extensions, performs no MIME-type or upload-capability check, and passes attacker-supplied files to move_uploaded_file(). Subscriber-level access is sufficient because the required nonce appears in the CMLOC_Editor_Images object on the front-end location editor.
