OpenClaw: Voice-call Plivo V3 webhook replay key uses unsorted URL, allowing replay via query-parameter reordering
Summary
Plivo V3 signature verification canonicalized query ordering, but replay detection hashed the raw verification URL. Reordering query parameters preserved a valid signature while producing a fresh replay-cache key.
Impact
An attacker who captured one valid signed Plivo V3 webhook could replay the same event by permuting query parameters and trigger duplicate voice-call processing.
