Summary
A critical flaw in Pipecat's LivekitFrameSerializer, an optional, non-default, undocumented serializer deprecated in version 0.0.90, passes untrusted WebSocket message data directly to pickle.loads() in deserialize() in src/pipecat/serializers/livekit.py. A remote client that can reach a server using this serializer, for example one bound to 0.0.0.0, can send a crafted pickle payload to execute arbitrary code on the server with the Pipecat service's privileges.
