Technical details
The vulnerability is a sensitive data disclosure (CWE-200) in the Rank Math SEO WordPress plugin. The plugin generates publicly accessible SEO metadata (meta description, OpenGraph, and Twitter tags) and an llms.txt file from post/product content without checking password-protection status. An unauthenticated attacker can read protected content by viewing page source to inspect meta tags or requesting /llms.txt directly. Password protection is completely bypassed—no authentication is required. The vulnerability affects posts, WooCommerce products, and custom post types enabled in llms.txt. Fixed in version 1.0.277.1, though a WooCommerce-related leak persists through product metadata.
