What is CVE-2026-77783?
The Rank Math SEO plugin for WordPress prior to version 1.0.277 fails to enforce visibility checks for posts when rendering schema. This oversight allows unauthorized users to access and disclose schema information for draft, pending, private, scheduled, and password-protected posts. As a result, sensitive content may be inadvertently revealed to unauthenticated visitors, potentially leading to unintended exposure of confidential data.
Affected Version(s)
Rank Math SEO 1.0.48 < 1.0.277
