Vulnerability from fkie_nvd - Published: 2025-10-25 07:15 - Updated: 2026-06-17 08:31
Severity
4.3 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
Summary
The FuseWP – WordPress User Sync to Email List & Marketing Automation (Mailchimp, Constant Contact, ActiveCampaign etc.) plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.1.23.0. This is due to missing or incorrect nonce validation on the save_changes function. This makes it possible for unauthenticated attackers to add or edit sync rules via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
