CVE-2026-1426Network attack vector

Author-level PHP object injection via shortcode deserialization

Published Feb 18, 2026 · Updated Feb 18, 2026

PHP object injection in BeRocket Advanced AJAX Product Filters 3.1.9.6 and earlier allows remote authenticated users to inject objects. The Live Composer compatibility layer's shortcode_check function deserializes untrusted shortcode data, creating attacker-chosen PHP objects. Author-level access and an active Live Composer plugin are required; file deletion, sensitive-data reads, or code execution also requires a usable POP chain from another installed component.
