FKIE_CVE-2026-104739

Vulnerability from fkie_nvd - Published: 2026-10-30 18:17 - Updated: 2026-10-30 19:17
Severity
4.9 (Medium) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N
Summary
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.
