Vulnerability Description
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.
