{"id":"CVE-2026-8684","state":"PUBLISHED","title":"MotoPress Hotel Booking <= 6.0.1 - Missing Authorization to Unauthenticated Arbitrary Booking Notes Modification via mphb_update_booking_notes AJAX Action","description":"The MotoPress Hotel Booking plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.0.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to overwrite or delete the internal notes (_mphb_booking_internal_notes) of any booking by supplying an arbitrary booking ID. The nonce for this action is output in the HTML source of every public page through wp_localize_script (MPHB._data.nonces), so any unauthenticated visitor can obtain a valid nonce and perform the action without any account or prior interaction.","publishedAt":"2026-05-22T07:50:26.756Z","updatedAt":"2026-05-22T12:18:21.512Z","severity":{"score":5.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["jetmonsters MotoPress Hotel Booking"],"affected":[{"vendor":"jetmonsters","product":"MotoPress Hotel Booking","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"6.0.1","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/6567e63c-3129-47b2-a734-733eb599821a?source=cve","https://plugins.trac.wordpress.org/browser/motopress-hotel-booking-lite/tags/6.0.1/includes/ajax-api/ajax-actions/update-booking-notes.php#L83","https://plugins.trac.wordpress.org/browser/motopress-hotel-booking-lite/tags/6.0.1/includes/ajax-api/ajax-actions/abstract-ajax-api-action.php#L34","https://plugins.trac.wordpress.org/browser/motopress-hotel-booking-lite/tags/6.0.1/includes/ajax-api/ajax-api-handler.php#L43","https://plugins.trac.wordpress.org/browser/motopress-hotel-booking-lite/tags/5.4.1/includes/ajax-api/ajax-actions/update-booking-notes.php#L83","https://plugins.trac.wordpress.org/browser/motopress-hotel-booking-lite/tags/5.4.1/includes/ajax-api/ajax-actions/abstract-ajax-api-action.php#L34","https://plugins.trac.wordpress.org/browser/motopress-hotel-booking-lite/tags/5.4.1/includes/ajax-api/ajax-api-handler.php#L43","https://plugins.trac.wordpress.org/changeset/3537354/motopress-hotel-booking-lite/trunk/includes/ajax-api/ajax-actions/update-booking-notes.php"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/8xxx/CVE-2026-8684.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-8684","state":"PUBLISHED","datePublished":"2026-05-22T07:50:26.756Z","dateUpdated":"2026-05-22T12:18:21.512Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-15T14:16:10.958Z"},"containers":{"cna":{"title":"MotoPress Hotel Booking <= 6.0.1 - Missing Authorization to Unauthenticated Arbitrary Booking Notes Modification via mphb_update_booking_notes AJAX Action","descriptions":[{"lang":"en","value":"The MotoPress Hotel Booking plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.0.1.
