CVE-2026-5394GHSA-9X44-4GXF-8C25

Pimcore is under investigation for a critical vulnerability that reportedly allows remote code execution and SQL injection via unvalidated DataObject class-definition field names.

What happened

An early warning has been issued for a critical vulnerability in Pimcore, identified as CVE-2026-5394 and tracked under GHSA-9X44-4GXF-8C25. This vulnerability appears to enable authenticated users with 'objects' permission to execute arbitrary PHP code and ALTER TABLE DDL, potentially leading to full server compromise. The vulnerability affects Pimcore versions >= 12.3.3, <= 12.3.3 or >= v12.3.3, <= v12.3.3. There is no indication that this vulnerability has been exploited in the wild at this time.

The vulnerability stems from insufficient validation of DataObject class-definition field names, allowing malicious input to be executed as PHP code or SQL commands. This could enable an attacker to gain unauthorized access to the server and manipulate the database. The issue is compounded by the fact that the 'objects' permission, which is required to exploit this vulnerability, is commonly granted to users in many Pimcore installations.
