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 8.7 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Service Exhaustion Flood (T1499.002); ranked at the 34.0th 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 are NIST 800-53 AC-3 (Access Enforcement) and SC-5 (Denial-of-service Protection).
Deeper analysis
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.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces authentication and validation of media-stream WebSocket upgrades before permitting connection establishment, blocking the unauthenticated socket creation that enables this CVE.
Implements denial-of-service protections that limit resource consumption from idle pre-authenticated WebSocket connections, directly mitigating the availability impact described in CVE-2026-32062.
Restricts the number of concurrent sessions a single unauthenticated client can hold open, reducing the ability to exhaust connection resources via the vulnerable WebSocket upgrade path.
