CVE-2022-1463Network attack vector

Arbitrary code execution via unsafe option unserialization

Published May 10, 2022 · Updated Feb 13, 2025

PHP object injection in wpdevelop Booking Calendar 9.1 and earlier allows remote attackers to inject objects through timeline options. The define_request_view_params_from_params function in core/timeline/v2/wpbc-class-timeline_v2.php passes attacker-controlled timeline_obj[options] or shortcode options to PHP unserialize without rejecting object data. Unauthenticated reachability requires a published timeline; otherwise authenticated shortcode access is required, and code execution depends on a compatible POP chain supplied by another installed component.
