CVE-2026-76547Network attack vectorHinoki check available

Administrator PHP object injection via unvalidated import

Published Aug 29, 2026 · Updated Aug 29, 2026

PHP object injection in Cozmoslabs Profile Builder before 4.0.1 allows remote authenticated users to instantiate objects through configuration imports. The Import and Export add-on deserializes uploaded configuration data without restricting the resulting type, so crafted serialized objects are instantiated. Administrator access and the disabled-by-default add-on are required; further impact also requires a usable POP gadget supplied by another installed plugin.
