Pimcore Admin Classic Bundle permissions are not getting checked when working with tags

Impact

You can create, delete etc. tags without having the permission to do so.
This vulnerability allows an attacker to perform broken access control and add tags to admin panel and add dumy data. One can do this as intruder and add text parameters with random numbers and this will effect integrity and availability.

Patches

Available in version 1.3.3.
