OpenClaw: Multiple Vulnerabilities

CVSS 9.4 CRITICAL

Risk Summary

OpenClaw before 2026.3.28 downloads and stores inbound media from Zalo channels before validating sender authorization. Unauthorized senders can force network fetches and disk writes to the media store by sending messages that are subsequently rejected. OpenClaw before 2026.3.28 contains a privilege escalation vulnerability in the /pair approve command path that fails to forward caller scopes into the core approval check. A caller with pairing privileges but without admin privileges can approve pending device requests asking for broader scopes including admin access by exploiting the missing scope validation in extensions/device-pair/index.ts and src/infra/device-pairing.ts. OpenClaw before 2026.3.28 contains a missing rate limiting vulnerability in the Nextcloud Talk webhook authentication that allows attackers to brute-force weak shared secrets. Attackers who can reach the webhook endpoint can exploit this to forge inbound webhook events by repeatedly attempting authentication without throttling.
