Pimcore is an open source data & experience management platform. Prior to version 10.1.1, Data Object CSV import allows formular injection. The problem is patched in 10.1.1. Aside from upgrading, one may apply the patch manually as a workaround.
This affects the package pimcore/pimcore before 10.0.7. This issue exists due to the absence of check on the storeId parameter in the method collectionsActionGet and groupsActionGet method within the ClassificationstoreController class.
