CVE-2026-101881 Details
Description
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.
A denial-of-service vulnerability has been identified in OpenClaw Windows Node versions prior to 2026.7.1. The issue arises from an unbounded resource allocation in the WebSocket transport of the gateway. This flaw allows connected gateways to send an endless stream of WebSocket continuation frames that do not include an 'EndOfMessage' indicator, leading to unlimited memory consumption. As a result, the node process can crash, causing a significant disruption.
Users can update to OpenClaw Windows Node version 2026.7.1 or later, where this vulnerability has been fixed.
