Description
BigBlueButton is an open-source virtual classroom. Prior to 3.0.29, BigBlueButton presenters could submit a presentationId through /api/graphql that identified a presentation belonging to another meeting. akka-bbb-apps/src/main/scala/org/bigbluebutton/core/apps/presentationpod/RemovePresentationPubMsgHdlr.scala did not verify the presentation-s meeting identifier before deletion, allowing a presenter who knew the identifier to delete another meeting-s presentation and disrupt its availability. This issue is fixed in version 3.0.29.
