Summary
Pimcore CMS/DXP version 12.3.8 contains a sandbox bypass vulnerability that allows authenticated administrative attackers to execute arbitrary methods on PHP objects. This vulnerability arises from improper implementations of checkMethodAllowed() and checkPropertyAllowed() in the custom Twig SecurityPolicy.
Risk Assessment
Attackers can exploit this vulnerability to perform arbitrary file reads, execute arbitrary database queries, and potentially achieve remote code execution, posing a serious security threat to the system.
Recommendation
It is recommended to upgrade to the latest version of Pimcore to mitigate this vulnerability and to review and strengthen the Twig security policy to limit attack vectors.

Original NVD description (English source)
Pimcore CMS/DXP version 12.3.8 contains a sandbox bypass vulnerability that allows authenticated administrative attackers to execute arbitrary methods on PHP objects by exploiting empty checkMethodAllowed() and checkPropertyAllowed() implementations in the custom Twig SecurityPolicy. Attackers can supply malicious Twig templates through the DataObject ClassDefinition Layout\Text component to perform arbitrary file reads, execute arbitrary database queries, and potentially achieve remote code execution via PHP object gadget chains, with the pimcore_* function wildcard further broadening the bypass to all Pimcore Twig functions.
