Search Atlas SEO – Premier SEO Plugin for One-Click WP Publishing & Integrated AI Optimization 2.4.4 - 2.5.12 - Missing Authorization to Authenticated (Subscriber+) Authentication Bypass via Account Takeover

The Search Atlas SEO – Premier SEO Plugin for One-Click WP Publishing & Integrated AI Optimization plugin for WordPress is vulnerable to authentication bypass due to a missing capability check on the 'generate_sso_url' and 'validate_sso_token' functions in versions 2.4.4 to 2.5.12. This makes it possible for authenticated attackers, with Subscriber-level access and above, to extract the 'nonce_token' authentication value to log in to the first Administrator's account.
