CVE-2024-24715Network attack vector

Unauthenticated price bypass via hidden-field manipulation

Published May 17, 2024 · Updated Apr 28, 2026

Price validation in The Events Calendar BookIt 2.4.0 and earlier allows remote attackers to reduce appointment charges via hidden fields. Published advisories do not identify the affected request parameter or the server-side operation that trusts the client-supplied amount. No account is required; a crafted booking submission can alter pricing and appointment data, while reported impacts are limited to low integrity and availability effects.
