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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-862"],"references":["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/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/trunk/includes/base/admin/booking/functions.php","https://plugins.trac.wordpress.org/changeset/3750085/wp-booking-system/trunk/includes/base/admin/booking/functions.php"],"products":[],"source":"nvd","synced_at":"2026-10-19T23:00:53.604569364+00:00"},"epss":{"cve":"CVE-2026-108123","score":0.00318,"percentile":0.24448,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
