NVD description
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.
What to do
- Upgrade OpenClaw to
2026.3.23or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
