Advisory

Source description from Wordfence Intelligence, credited to Project Black.

The Rank Math SEO – AI SEO Tools to Dominate SEO Rankings plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to 1.0.277.1. This is due to missing post_password_required() checks before using post content to generate SEO metadata. This makes it possible for unauthenticated attackers to read the content of password-protected posts via publicly generated SEO metadata such as schema blocks, meta descriptions, and Open Graph data.
