What is CVE-2026-44118?

The OpenClaw vulnerability allows unauthorized loopback clients to impersonate the owner by manipulating the sender-owner header metadata derived from server-issued bearer tokens. This can lead to unauthorized access to operations restricted to the owner, as it bypasses owner-gated functionality. Users and administrators of OpenClaw versions prior to 2026.4.22 should review and apply recommended patches to mitigate this security risk.
