CVE-2026-16062 Event Booking Manager for WooCommerce CVE debrief

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