CVE-2026-32062
Published: 11 March 2026
Summary
CVE-2026-32062 is a high-severity Allocation of Resources Without Limits or Throttling (CWE-770) vulnerability in Openclaw Openclaw. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Service Exhaustion Flood (T1499.002); ranked at the 33.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
This control implements explicit throttling on session allocation, addressing the weakness of allocating resources without limits.
Plan testing exercises resource allocation limits and throttling during simulated failures, directly addressing weaknesses that allow unbounded resource use.
Contingency plan updates ensure recovery strategies address unbounded resource allocation, making it harder for attackers to exploit lack of throttling to cause prolonged outages.
Provides continuity when unbounded resource allocation at the primary site leads to exhaustion and downtime.
Alternate services allow operations to continue when primary allocation of resources lacks limits or throttling.
Explicit planning of security-related actions requires defining limits, windows, and resource allocations, making allocation without throttling far less likely.
Measures of performance include tracking allocation behavior and throttling effectiveness, reducing the window for resource exhaustion attacks.
Imposes an inactivity-based limit on network resource allocation, throttling the number of concurrently held connections.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Vulnerability directly enables unauthenticated WebSocket connection holding to exhaust server resources, matching service exhaustion flood for endpoint DoS.
NVD Description
OpenClaw versions2026.2.21-2 prior to 2026.2.22 and @openclaw/voice-call versions 2026.2.21 prior to 2026.2.22 accept media-stream WebSocket upgrades before stream validation, allowing unauthenticated clients to establish connections.

Deeper analysisAI
CVE-2026-32062, published on 2026-03-11, affects OpenClaw versions 2026.2.21-2 prior to 2026.2.22 and @openclaw/voice-call versions 2026.2.21 prior to 2026.2.22. The vulnerability arises from the acceptance of media-stream WebSocket upgrades before stream validation, enabling unauthenticated clients to establish connections. It carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and is associated with CWE-770 (Allocation of Resources Without Limits or Throttling).
Remote attackers require no privileges or user interaction to exploit this issue over the network with low complexity. By initiating WebSocket upgrades for media streams, they can hold idle pre-authenticated sockets open indefinitely, consuming server connection resources and degrading service availability for legitimate streams, resulting in a denial-of-service condition.
Mitigation is detailed in the GitHub security advisory GHSA-mfg5-7q5g-f37j, the fix commit 1d8968c8a821ff1a05c294a1846b3bcb6f343794, and the VulnCheck advisory on unauthenticated WebSocket resource exhaustion. Affected deployments should update to OpenClaw version 2026.2.22 or later to address the validation timing issue.
