FKIE_CVE-2025-6688

Vulnerability from fkie_nvd - Published: 2025-06-27 08:15 - Updated: 2026-06-17 10:02
Severity
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
The Simple Payment plugin for WordPress is vulnerable to Authentication Bypass in versions 1.3.6 to 2.3.8. This is due to the plugin not properly verifying a user's identity prior to logging them in through the create_user() function. This makes it possible for unauthenticated attackers to log in as administrative users.
