Detailed vulnerability description
The vulnerability allows a remote attacker to trigger duplicate or stale call-state transitions.
The vulnerability exists due to authentication bypass by capture-replay in the voice-call Twilio webhook handling and manager dedupe logic when processing replayed webhook events. A remote attacker can replay a previously captured webhook event to trigger duplicate or stale call-state transitions.
A replayed event could be treated as new because normalized event IDs were randomized on each parse.
