No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

OpenClaw 2026.2.25 before 2026.5.26 allow a lower-trust caller or configured input path to bypass non-browser rate limits on WebSocket authentication attempts. When the affected feature is enabled and reachable by lower-trust input, this can consume gateway resources and reduce service availability.
