Detailsinfo

A vulnerability, which was classified as critical, has been found in Pimcore up to 2026.1.4. Affected by this issue is the function Block::load of the file models/DataObject/ClassDefinition/Data/Block.php of the component ClassDefinition. The manipulation of the argument ClassDefinition UID with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Pimcore is an Open Source Data & Experience Management Platform. Prior to 2026.1.5, an authenticated user with the objects permission can submit a malicious ClassDefinition UID because the name and ID validation expressions in models/DataObject/ClassDefinition.php validate only the beginning of each value. When a data object of that class containing a Block field is loaded, Block::load in models/DataObject/ClassDefinition/Data/Block.php incorporates the stored class ID into an unquoted object table identifier, allowing the UID to supply SQL syntax. The resulting query can read or modify arbitrary Pimcore database tables, including disclosure of password hashes, and the flaw represents an incomplete validation hardening because earlier work added a start anchor without enforcing the end of the identifier. This issue is fixed in version 2026.1.5.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-55072 since 06/16/2026. The exploitation is known to be easy. The attack may be launched remotely. There are known technical details, but no exploit is available.
