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.

What it is to other things

In words only, so not counted until a person confirms one:

affects	`openclaw/openclaw_windows_node` NVD says “OpenClaw · OpenClaw Windows Node”
made_by	`openclaw` NVD says “OpenClaw”

Every value, with what each source said and its receipt

Property Source Said Means here

Automatable

At least one of those steps needs a person.

vulnerability

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. zetlyn/cve-nvd · 2026-09-30	automatable no cvss 6.5 cvss4 7.1 cvss4_vector CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X cvss_vector CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H cwe CWE-770 exploitation poc fixed_in 2026.7.1 product OpenClaw Windows Node severity MEDIUM status Deferred technical_impact partial vendor OpenClaw	source
