What is CVE-2026-101881?

OpenClaw Windows Node prior to version 2026.7.1 is susceptible to a denial of service attack due to improper resource allocation in the WebSocket transport. By sending a continuous stream of WebSocket continuation frames that lack an EndOfMessage signal, attackers can trigger unlimited memory growth, leading to the eventual crashing of the node process. This vulnerability poses a significant risk to services relying on OpenClaw for WebSocket communications.

Affected Version(s)

OpenClaw Windows Node 0 < 2026.7.1
