CVE-2026-101881: OpenClaw Windows Node before 2026.7.1 Denial of Service
OpenClaw Windows Node before 2026.7.1 contains an allocation of resources without limits vulnerability in the gateway WebSocket transport that allows connected gateways to exhaust node memory. Attackers can send an unending sequence of WebSocket continuation frames without EndOfMessage to cause unbounded memory growth until the node process crashes.

Event History
Frequently Asked Questions
Which systems are exposed to this denial-of-service issue?
OpenClaw Windows Node installations before version 2026.7.1 are affected where a gateway can establish a WebSocket connection to the node's gateway transport. The attacker must be a connected gateway and requires low privileges.
What does an attacker need to send to trigger the crash?
The attacker sends a continuous sequence of WebSocket continuation frames without an EndOfMessage indicator. This causes unbounded memory growth until the node process crashes.
What is the remediation?
Upgrade OpenClaw Windows Node to version 2026.7.1 or later. The issue is addressed in the v2026.7.1 release.
