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.","published":"2026-10-17T04:16:48.427","modified":"2026-10-17T04:16:48.427","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-booking-system/tags/2.1.0.2/includes/base/admin/booking/functions.php#L244"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-booking-system/tags/2.1.0.2/includes/base/admin/booking/functions.php#L250"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-booking-system/tags/2.1.0.2/includes/base/admin/functions.php#L30"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-booking-system/trunk/includes/base/admin/booking/functions.php"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3750085/wp-booking-system/trunk/includes/base/admin/booking/functions.php"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a86fab4a-71ec-4006-96f0-46202de2f389?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-17T04:16:48.427"}}
