Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Pimcore CMS (package pimcore/pimcore) versions up to 11.5.14.1 and 12.0.0-RC1 through 12.3.8 have a Twig sandbox bypass because the custom SecurityPolicy's checkMethodAllowed and checkPropertyAllowed checks are empty. An authenticated administrator can supply malicious Twig templates through the DataObject ClassDefinition Layout Text component to read arbitrary files, run arbitrary database queries, and potentially reach remote code execution through PHP object gadget chains. No fixed version is listed.
