CVE-2026-32062: OpenClaw 2026.2.21-2 < 2026.2.22 - Unauthenticated WebSocket Resource Exhaustion via Media Stream
OpenClaw versions 2026.2.21-2 up to, but not including, 2026.2.22, and @openclaw/voice-call versions 2026.2.21 up to, but not including, 2026.2.22 accept media-stream WebSocket upgrades before stream validation, allowing unauthenticated clients to establish connections. Remote attackers can hold idle pre-authenticated sockets open to consume connection resources and degrade service availability for legitimate streams.
Security readout for executives and security teams
Plain-English summary
OpenClaw’s media-stream WebSocket handling can let unauthenticated remote clients hold connections open before validation. That can exhaust connection capacity and degrade availability for legitimate voice or media streams. The issue is high severity because exploitation requires network access only and no credentials or user interaction.
Executive priority
Treat this as a high-priority availability risk for OpenClaw deployments supporting live media or voice operations. It should be remediated promptly on exposed systems because unauthenticated remote clients can degrade service without needing accounts or user interaction.
Technical view
OpenClaw before 2026.2.22 and @openclaw/voice-call before 2026.2.22 accepted media-stream WebSocket upgrades before stream validation. The weakness maps to CWE-770: allocation of resources without limits or throttling. Impact is availability loss, reflected by CVSS 4.0 score 8.7 with high vulnerable-system availability impact.
Likely exposure
Exposure is most likely where OpenClaw media or voice-call services are reachable over the network, especially from the internet. Systems already running 2026.2.22 or later are not indicated as affected by the provided sources.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The described attack does not require authentication, privileges, user interaction, or high complexity, but the provided material frames the outcome as resource exhaustion rather than code execution or data theft.
Researcher notes
Focus validation on version exposure and WebSocket upgrade handling around media-stream validation. The provided sources support a pre-authenticated resource exhaustion condition and a fixed release, but do not provide KEV status, public exploit confirmation, or broader product impact beyond OpenClaw and @openclaw/voice-call.
Mitigation direction
Upgrade OpenClaw to 2026.2.22 or later.
Upgrade @openclaw/voice-call to 2026.2.22 or later.
Prioritize upgrades for internet-facing media-stream or voice-call deployments.
Review the GitHub advisory and patch commit for vendor-confirmed fix details.
If upgrading is delayed, check vendor guidance before relying on compensating controls.
Validation and detection
Inventory deployed OpenClaw and @openclaw/voice-call package versions.
Confirm affected services are running 2026.2.22 or later.
Identify whether media-stream WebSocket endpoints are reachable externally.
Review connection metrics for unusual idle pre-authenticated WebSocket volume.
After upgrade, confirm legitimate media streams still establish normally.

These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.
