CVE-2026-77782 · Severity: medium · CVSS 5.3 · Published 2026-09-02

Rank Math SEO, a popular WordPress plugin that optimizes website content for search engines, fails to respect password protection on posts and products. An unauthenticated attacker can view sensitive content from password-protected pages by examining the plugin's auto-generated metadata tags or by accessing the plugin's llms.txt file, bypassing the password protection entirely and exposing confidential information like payroll data or unreleased product details.

## 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.
