Vulnerability details

The vulnerability allows a remote user to escalate privileges by moving or publishing entries into sections they cannot edit.

The vulnerability exists due to improper access control in the control panel inline-edit endpoint `element-indexes/save-elements` when handling client-supplied entry attributes. A remote user can send a specially crafted request that changes `sectionId` and `typeId` to escalate privileges by moving or publishing entries into unauthorized sections.

By duplicating an entry in a permitted section before the move, the issue can effectively be used to publish arbitrary entries into another section.
