Deserialization in Event Booking Manager For Woocommerce
CVE-2026-16062

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.
