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.\n\n## Affected\n\n- `wp_booking_system_booking_calendar <= 2.1.0.3`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"midnight","depthScore":53,"depthScoreParts":{"impact":41.3,"likelihood":0.2,"exploitation":12,"ransomware":0},"changes":[{"seq":232822,"id":"CVE-2026-108123","ts":1793892632854,"field":"exploit_available","old":"false","new":"true"}]}
