FKIE_CVE-2026-8903

Vulnerability from fkie_nvd - Published: 2026-05-27 07:16 - Updated: 2026-05-27 14:50
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 Two-factor authentication (formerly IP Vault) plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1. This is due to missing or incorrect nonce validation on the ipv_save_changes function. This makes it possible for unauthenticated attackers to modify the plugin's firewall and two-factor authentication settings — including the operating mode, request include/exclude rules, authentication slug, and log retention period — potentially disabling protection entirely via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
