CVE-2026-15946: Search Atlas SEO <= 2.6.23 - Missing Authorization to Authenticated (Subscriber+) Whitelabel Password Modification via handle_whitelabel_password_early Function

Published Sep 19, 2026

Updated

The Search Atlas SEO – Premier SEO Plugin for One-Click WP Publishing & Integrated AI Optimization plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.6.23. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite the whitelabel settings password to an attacker-controlled value, enabling them to unlock whitelabel-protected admin settings tabs including whitelabel, general, and advanced configuration.
