CVE-2025-14390: Videomerchant Video Merchant

High severity, CVSS 8.8. EPSS: 0.4% chance of exploitation in the next 30 days.

The Video Merchant plugin for WordPress is vulnerable to Cross-Site Request Forgery in version <= 5.0.4. This is due to missing or incorrect nonce validation on the video_merchant_add_video_file() function. This makes it possible for unauthenticated attackers to upload arbitrary files that make remote code execution possible via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

Affected products
