GCVE Workshop - 22 September 2026 (14:00-18:00), Luxembourg Before The Vulnopticon Conference - Registration

FKIE_CVE-2023-5383

Vulnerability from fkie_nvd - Published: 2023-11-22 16:15 - Updated: 2026-06-17 06:48
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
Summary
The Funnelforms Free plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.4. This is due to missing or incorrect nonce validation on the fnsf_copy_posts function. This makes it possible for unauthenticated attackers to create copies of arbitrary posts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. CVE-2023-5990 appears to be a duplicate of this issue.
