Impact

If backend admin controllers are called with a certain notation, the ACL could be bypassed. Users could execute actions, which they are normally not able to do.

Patches

We recommend updating to the current version 5.7.15. You can get the update to 5.7.15 regularly via the Auto-Updater or directly via the download overview.
