CVE-2026-101881: Allocation of Resources Without Limits or Throttling in OpenClaw OpenClaw Windows Node
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.
AI Analysis
Technical Summary
OpenClaw Windows Node prior to version 2026.7.1 contains a vulnerability in its gateway WebSocket transport where resource allocation is not limited or throttled. This flaw allows an attacker with at least low privileges to send a continuous stream of WebSocket continuation frames lacking the EndOfMessage indicator, leading to unbounded memory consumption. The memory exhaustion ultimately causes the node process to crash, resulting in denial of service.
Potential Impact
Successful exploitation leads to unbounded memory growth on the affected node, causing the node process to crash and resulting in denial of service. There is no indication of privilege escalation, data disclosure, or code execution from the provided data.
Mitigation Recommendations
A fix is available in OpenClaw Windows Node version 2026.7.1. Users should upgrade to this version or later to remediate the vulnerability. No other mitigation guidance is provided.
