Authenticated post metadata disclosure via unchecked shortcode lookup
Published Apr 15, 2024 · Updated Aug 1, 2024
Improper access control in Meta Box before 5.9.4 allows remote authenticated users to read custom fields from other users' posts. The rwmb_meta shortcode accepts attacker-chosen object_id and field-key values and renders the referenced post metadata without verifying access to that post. Contributor access and a site-defined Meta Box field are required; disclosure is limited to metadata whose post ID and field key can be identified or guessed.
