CVE-2026-41395: OpenClaw: Voice-call Plivo V3 webhook replay key uses unsorted URL, allowing replay via query-parameter reordering

March 31, 2026 (updated April 28, 2026)

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.
