CVE-2023-51470Network attack vector

Authenticated PHP object injection via SearchResultP deserialization

Published Dec 29, 2023 · Updated Apr 28, 2026

PHP object injection in Jacques Malgrange Rencontre – Dating Site 3.11.1 and earlier allows remote authenticated users to inject PHP objects. The plugin deserializes attacker-controlled SearchResultP request data without restricting which PHP classes may be instantiated. Subscriber-level access is required; the plugin has no native POP chain, but a chain supplied by another plugin or theme enables file deletion, data disclosure, or code execution.
