CVE-2025-12075 is a missing authorization vulnerability in the Order Splitter for WooCommerce WordPress plugin. The vulnerability arises from the lack of a capability check on the 'wos_troubleshooting' AJAX endpoint, which permits authenticated users with minimal privileges (Subscriber-level and above) to view order data of other users. This issue affects all plugin versions up to and including 5.3.5. The CVSS 3.1 score of 4.3 reflects a medium severity with network attack vector, low attack complexity, and limited confidentiality impact. No known exploits are reported in the wild, and no patch or official fix has been documented.

An attacker with Subscriber-level access or higher can exploit this vulnerability to gain unauthorized read access to order information of other users on the affected WooCommerce site. This could lead to exposure of sensitive order-related data, but does not affect integrity or availability of the system. The impact is limited to confidentiality loss of order information.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict user roles and permissions to trusted users only and consider disabling or restricting access to the 'wos_troubleshooting' AJAX endpoint if possible. Monitor for updates from the plugin vendor Fahadmahmood and apply patches promptly once available.
