Overview

CVE-2026-16601 is a high-severity vulnerability. It was published on August 25, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

The CM Map Locations – Visualize and share your locations in a few clicks plugin for WordPress is vulnerable to Limited Arbitrary File Upload in all versions up to, and including, 2.1.8 via the uploadMedia function. This is due to insufficient file type validation in the upload handler, which performs incomplete extension filtering without MIME-type checks or upload capability verification before passing attacker-supplied files to move_uploaded_file(). This makes it possible for authenticated attackers, with subscriber-level access and above, to upload files that may be executable, which makes remote code execution possible. The required nonce is exposed to any logged-in Subscriber via the CMLOC_Editor_Images JavaScript object on the front-end location editor page.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
