CVE-2026-87840Network attack vector

Unauthenticated booking tampering via unrestricted AJAX actions

Published Sep 20, 2026 · Updated Sep 20, 2026

Improper access control in Refresh Themes Tripzzy before 1.5.1 allows remote attackers to alter arbitrary booking data. Administrative booking and booking-note AJAX actions omit capability and booking-ownership checks, while an anonymous visitor can obtain the token that gates them. Any remote visitor who obtains that token can change booking contents, stored totals, and notes, compromising booking-data integrity.
