Unauthenticated object injection via gallery shortcode deserialization
Published Aug 20, 2025 · Updated Apr 28, 2026
PHP object injection in MediCenter 15.1 and earlier allows remote attackers to inject objects through a public WordPress AJAX action. The mc_theme_gallery_shortcode function passes attacker-controlled GET atts data through stripslashes into unserialize without disabling object instantiation. No authentication is required; file deletion, sensitive-data retrieval, or code execution additionally requires a usable POP chain from another installed component.
