Vulnerability in WP Map Block – Google Maps, OpenStreetMap, Mapbox, Store & Shop Locator, Directory, Listings & Filters — CVE-2026-19798
What to do now
Update WP Map Block – Google Maps, OpenStreetMap, Mapbox, Store & Shop Locator, Directory, Listings & Filters to 3.1.0 or later.
Affected versions
- Everything up to and including 3.0.0
Affected: WP Map Block – Google Maps, OpenStreetMap, Mapbox, Store & Shop Locator, Directory, Listings & Filters (plugin, wp-map-block)
What the vulnerability is
The Wp Map Block plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the set_status() and bulk() functions in the Maps_Controller REST controller in versions up to, and including, 3.0.0. The plugin's permission_callback (can_edit()) only verifies current_user_can('edit_posts') and performs no object-level ownership check or verification of publish-level capabilities, while the handlers pass the caller-controlled map ID directly to wp_update_post() (and wp_delete_post() in the bulk delete branch) to change post_status between publish and draft. This makes it possible for authenticated attackers, with Contributor-level access and above, to publish or unpublish (and bulk-delete) any wpmb_map post, including maps owned by administrators, which hides published maps from all public pages site-wide or forces draft maps to become publicly visible.
