## Technical details

The LinkSetController.php fails to properly validate user authorization when processing the linkset delete, detach, and get-remote-object routes. An authenticated console user can supply arbitrary class and key parameters to these endpoints to perform operations on objects they lack permission to access. This is an authorization bypass affecting the delete, detach, and read functions on linked objects.
