CVE-2020-35939Network attack vector

Authenticated PHP object injection via layout import

Published Jan 1, 2021 · Updated Aug 4, 2024

PHP object injection in PickPlugins Team Showcase before 1.22.16 allows remote authenticated users to inject PHP objects via an AJAX request. The team_import_xml_layouts function fetches the source URL and unserializes attacker-controlled post metadata without validation. Subscriber-level access is normally required, and code execution or file modification additionally requires an installed gadget with a vulnerable magic method.
