Admin-level PHP object injection via settings import

Published May 8, 2023 · Updated Feb 4, 2025

PHP object injection in Beaver Builder Customizer Export/Import before 0.9.6 allows remote authenticated users to inject objects via settings import. The Customizer import handler passes attacker-controlled uploaded settings content to PHP unserialization without restricting object creation. Administrator access and a suitable gadget chain are required; successful exploitation can read or delete files, expose data, or execute code.
