OpenClaw < 2026.3.23 - Replay Identity Drift via Query-Only Variants in Plivo V2 Verification

Published Apr 9, 2026

Modified 3 weeks ago

Details

OpenClaw before 2026.3.23 contains a replay identity vulnerability in Plivo V2 signature verification that allows attackers to bypass replay protection by modifying query parameters. The verification path derives replay keys from the full URL including query strings instead of the canonicalized base URL, enabling attackers to mint new verified request keys through unsigned query-only changes to signed requests.
