Summary

CVE-2026-62210 is a medium-severity Allocation of Resources Without Limits or Throttling (CWE-770) vulnerability in Openclaw Openclaw. Its CVSS base score is 6.0 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Application Exhaustion Flood (T1499.003); ranked at the 24th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-5 (Denial-of-service Protection) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Vulnerability Data

OpenClaw versions before 2026.6.1 contain a denial of service vulnerability where remote media URLs can trigger slow-read attacks that exhaust gateway worker resources. Attackers with access to configured input paths can supply remote media URLs that consume gateway resources and…

T1499.003 Application Exhaustion Flood Impact
Adversaries may target resource intensive features of applications to cause a denial of service (DoS), denying availability to those applications.
Why these techniques?

CWE-770 resource exhaustion via slow-read on remote URLs directly enables application-layer DoS against gateway workers.

Mitigating Controls (NIST 800-53 r5) AI

preventdetect

Directly mitigates resource-exhaustion DoS from slow-read remote media URLs by enforcing limits and throttling on gateway workers.

prevent

Requires validation of supplied remote media URLs to reject malformed or abusive inputs that trigger unbounded resource allocation (CWE-770).

prevent

Restricts which users or processes may supply remote media URLs via configured input paths, reducing the attack surface for resource exhaustion.

detects

Baseline comparison of CPU, memory and bandwidth usage helps surface uncontrolled resource allocations before they cause service degradation.

prevents

Capacity projections and elasticity measures ensure that allocation requests are bounded and can be throttled, reducing the window in which an attacker can force unbounded resource reservations.

mitigates

Defining retention periods and deletion schedules for backup copies prevents indefinite accumulation of data on storage media without corresponding resource-management controls.

mitigates

Architectural redundancy and automatic failover limit the impact of an attacker who forces excessive allocations, because spare capacity can absorb the load until the primary instance recovers.

none

Documented incident response procedures that include activation of continuity plans and controlled recovery help ensure that resource consumption triggered by an incident is bounded and managed rather than left unbounded.

none

Mandating tested continuity procedures that preserve or replace resource-limiting controls prevents an attacker from exploiting the absence of throttling mechanisms during an outage.
