CVE-2026-104739 Details
Description
The JS Help Desk – AI-Powered Support & Ticketing System plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the setSupportCustomImage function in all versions up to, and including, 5.0.1. This makes it possible for authenticated attackers, with administrator-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Exploitation requires a two-step sequence: an administrator first saves a traversal-crafted value in the support_custom_img configuration field, then triggers deletion by uploading a new support custom image, at which point setSupportCustomImage() resolves and deletes the attacker-controlled path.
A vulnerability allowing arbitrary file deletion has been identified in the JS Help Desk – AI-Powered Support & Ticketing System plugin for WordPress, affecting all versions through 5.0.1. The issue arises from inadequate file path validation in the setSupportCustomImage function, enabling authenticated attackers with administrator-level access to delete arbitrary files on the server. This deletion can lead to remote code execution if critical files, such as wp-config.php, are removed. Exploitation involves a two-step process: first, an administrator must save a crafted traversal value in the support_custom_img configuration field, and then upload a new support custom image, prompting the deletion of the specified file path.
Users are advised to update the JS Help Desk – AI-Powered Support & Ticketing System plugin to version 5.0.2 or a newer patched version.
