Description (CNA)
OpenClaw before 2026.3.28 contains a webhook replay vulnerability in Plivo V3 signature verification that canonicalizes query ordering for signatures but hashes raw URLs for replay detection. Attackers can reorder query parameters to bypass replay cache detection and trigger duplicate voice-call processing with a captured valid signed webhook.
