{"id":"CVE-2026-108123","state":"PUBLISHED","title":"WP Booking System <= 2.1.0.3 - Missing Authorization to Unauthenticated Sensitive Information Disclosure via 'wpbs_action=email_logs' Action","description":"The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.0.3 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 read the stored notification email body of any booking by iterating booking_id and email_log_id, exposing customer PII including names, email addresses, phone numbers, messages, and booking dates intended to be visible only to administrators. This is exploitable by any Subscriber-level user because admin_init fires on profile.php, a wp-admin page accessible to all authenticated users.","publishedAt":"2026-10-17T03:43:29.401Z","updatedAt":"2026-10-18T11:22:46.479Z","severity":{"score":7.5,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["murgroland WP Booking System – Booking Calendar"],"affected":[{"vendor":"murgroland","product":"WP Booking System – Booking Calendar","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"2.1.0.3","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a86fab4a-71ec-4006-96f0-46202de2f389?source=cve","https://plugins.trac.wordpress.org/browser/wp-booking-system/tags/2.1.0.2/includes/base/admin/booking/functions.php#L250","https://plugins.trac.wordpress.org/browser/wp-booking-system/tags/2.1.0.2/includes/base/admin/functions.php#L30","https://plugins.trac.wordpress.org/browser/wp-booking-system/tags/2.1.0.2/includes/base/admin/booking/functions.php#L244","https://plugins.trac.wordpress.org/browser/wp-booking-system/trunk/includes/base/admin/booking/functions.php","https://plugins.trac.wordpress.org/changeset/3750085/wp-booking-system/trunk/includes/base/admin/booking/functions.php"],"weaknesses":["CWE-862"],"ingestedAt":"2026-10-29T20:10:33.477Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/108xxx/CVE-2026-108123.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-108123","state":"PUBLISHED","datePublished":"2026-10-17T03:43:29.401Z","dateUpdated":"2026-10-18T11:22:46.479Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-10-09T14:24:17.800Z"},"containers":{"cna":{"title":"WP Booking System <= 2.1.0.3 - Missing Authorization to Unauthenticated Sensitive Information Disclosure via 'wpbs_action=email_logs' Action","descriptions":[{"lang":"en","value":"The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.1.0.3 This is due to the plugin not properly verifying that a user is authorized to perform an action.
