CVE-2026-45162Public exploitNetwork attack vector

Code execution via unrestricted PHP deserialization

Published Jul 17, 2026 · Updated Jul 17, 2026

Unsafe deserialization in affected Pimcore releases allows remote authenticated users to execute code through a writable data source. Six core and Admin Classic locations pass database or filesystem values to PHP unserialize() without restricting allowed classes, instantiating autoloadable gadget classes. Exploitation requires high privileges and control of a serialized data source through a separate SQL injection or file-write path; successful chains execute with web-server privileges.
