CVE-2025-14390Network attack vector

Remote code execution via faulty upload nonce validation

Published Dec 10, 2025 · Updated Dec 10, 2025

Cross-site request forgery in Video Merchant 5.0.4 and earlier allows remote attackers to upload arbitrary files through an administrator's browser. The video_merchant_add_video_file() function processes the upload action without correct nonce validation, so a forged request can place an attacker-chosen file on the server. Exploitation requires a site administrator to perform the forged action, after which an executable upload enables remote code execution.
