# DooTask: missing membership check lets users read and post OKR messages

DooTask through 1.9.66 skips the membership check for dialogs with group type 'okr' in WebSocketDialog::checkDialog(). An authenticated user who supplies the dialog_id of an OKR comment dialog can read and inject messages through the message list and send endpoints.

_Summary, check and fix written by a model from the sources; labelled as such._
