CVE-2026-12378Network attack vector

Unauthenticated object injection via unsafe PHP deserialization

Published Jul 8, 2026 · Updated Jul 8, 2026

PHP object injection in BookingPress before 1.5.6 allows remote attackers to inject arbitrary PHP objects via unvalidated data. The published record does not identify the affected request parameter or deserialization call; it states that the plugin passes unvalidated data to a PHP deserialization function. Code execution requires a suitable PHP gadget chain on the WordPress site, so object injection is unconditional but remote code execution is environment-dependent.
