Private post disclosure via unchecked shortcode target
Published Nov 17, 2021 · Updated Aug 3, 2024
Incorrect authorization in Paul Ryan Insert Pages before 3.7.0 allows remote authenticated users to read private post content via a shortcode. The insert shortcode accepts another author's private post slug and renders its content and metadata without enforcing the caller's read permission. Contributor access and knowledge of the target slug are required; password-protected posts and pages are not exposed.
