CVE-2023-51700

Code execution via stored OrderResponse deserialization

Published Dec 27, 2023 · Updated Nov 27, 2024

Object injection in Unofficial Mobile BankID Integration for WordPress before 1.0.1 allows local users to execute code via database tampering. getAuthResponseFromDB() passes the stored OrderResponse response field directly to PHP unserialize(), enabling crafted objects to instantiate gadget chains. Exploitation requires high-privilege access to alter the plugin's database records and can execute code, modify data, or expose WordPress data.
