Editor-level PHP object injection
Published Sep 30, 2026 · Updated Sep 30, 2026
PHP object injection in Page Builder by SiteOrigin 2.36.0 and earlier allows remote authenticated users to inject PHP objects through the editor. The available public sources do not identify the editor input or deserialization operation responsible for the reported injection. Editor-level access is the stated gate; no retrieved source establishes a gadget chain or a resulting ability to read data, execute code, or interrupt service.
