CVE-2026-16062: Insecure Deserialization (CVSS 6.6)

Description

The Event Booking Manager for WooCommerce WordPress plugin before 5.3.7 does not prevent the deserialization of user-controlled input in some of its event content fields, allowing users with Contributor-level access and above to inject PHP objects. No POP chain is present in the Event Booking Manager for WooCommerce WordPress plugin before 5.3.7 itself, but if one is present via another installed Event Booking Manager for WooCommerce WordPress plugin before 5.3.7 or , this could lead to actions such as arbitrary file deletion, sensitive data retrieval, or remote code execution. This is an incomplete fix of the Event Booking Manager for WooCommerce WordPress plugin before 5.3.7's earlier object-injection advisories.
