CVE-2025-13088 is a Local File Inclusion vulnerability in the Category and Product Woocommerce Tabs plugin for WordPress, affecting all versions up to and including 1.0. The vulnerability arises from improper control of the 'template' parameter in the categoryProductTab() function, allowing authenticated users with contributor or higher privileges to include and execute arbitrary PHP files on the server. This can lead to full compromise of the affected system. The CVSS 3.1 base score is 8.8, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and high impact on confidentiality, integrity, and availability. No patch or official fix is currently available, and the plugin is not a cloud service.

Successful exploitation allows an authenticated attacker with contributor-level access or higher to execute arbitrary PHP code on the server hosting the vulnerable WordPress plugin. This can lead to complete system compromise, including unauthorized data access, modification, and potential denial of service. The high CVSS score (8.8) reflects the critical nature of this vulnerability affecting confidentiality, integrity, and availability.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or removing the vulnerable plugin to prevent exploitation.
