This is due to missing ownership verification in the REST API routes registered via `Mappress_Api::rest_api_init()`, where the GET `/wp-json/mapp/v1/maps/{mapid}` endpoint uses `'permission_callback' => '__return_true'` and the write endpoints (POST update, DELETE, PATCH mutate, POST clone, POST empty_trash) only check the generic `edit_posts` capability without confirming that the requester owns the targeted map — a gap that is not compensated at the model layer, as `Mappress_Map::get()`, `save()`, `delete()`, `mutate()`, and `empty_trash()` all operate on any caller-supplied map ID without an ownership check. This makes it possible for unauthenticated attackers to read sensitive map data — including POI titles, addresses, coordinates, and body content — for any map on the site by enumerating map IDs, and for authenticated attackers with Contributor-level access and above to modify, delete, trash/restore, or clone any map regardless of its author.","published_at":"2026-06-06T03:28:25.116000Z","last_modified_at":null,"cvss_v3_score":5.3,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-639"],"nvd_references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/9f402aa7-24d6-448b-a1d3-5ee7c90b39bc?source=cve","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_api.php#L328","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_api.php#L328","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_api.php#L90","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_api.php#L268","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_api.php#L39","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_api.php#L253","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_api.php#L50","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_api.php#L75","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_map.php#L239","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_map.php#L493","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_map.php#L379","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.96.6/mappress_map.php#L550","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_api.php#L90","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_api.php#L268","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_api.php#L39","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_api.php#L253","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_api.php#L50","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_api.php#L75","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_map.php#L239","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_map.php#L493","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_map.php#L379","https://plugins.trac.wordpress.org/browser/mappress-google-maps-for-wordpress/tags/2.95.10/mappress_map.php#L550","https://plugins.trac.wordpress.org/changeset?old_path=/mappress-google-maps-for-wordpress/tags/2.96.6&new_path=/mappress-google-maps-for-wordpress/tags/2.97.1"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:31:10.822903Z"},"effective_severity":"MEDIUM","badges":["poc"],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack
