How severe is CVE-2026-32062?

No CVSS score has been assigned to CVE-2026-32062 yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by CVE-2026-32062?

CVE-2026-32062 affects the following packages: openclaw (npm), @openclaw/voice-call (npm). Ecosystems affected: npm.

How do I fix CVE-2026-32062?

Update openclaw to 2026.2.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-32062 is resolved across your whole dependency graph.

How do I detect CVE-2026-32062 in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2026-32062 if there is no patch (or I can't update yet)?

Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.

Is CVE-2026-32062 actively exploited in the wild?

No public exploit code has been indexed for CVE-2026-32062 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2026-32062?

CVE-2026-32062 has an EPSS (Exploit Prediction Scoring System) score of 0.4%, placing it in the 38th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is CVE-2026-32062?

CVE-2026-32062 is classified as CWE-770 (CWE-770). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was CVE-2026-32062 published, and has it been updated?

CVE-2026-32062 was published on March 11, 2026 and was last updated on October 28, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

Summary

@openclaw/voice-call (and the bundled copy shipped in openclaw) accepted media-stream WebSocket upgrades before stream validation. In reachable deployments, unauthenticated pre-start sockets could be held open and increase resource pressure.

Affected Packages / Versions

openclaw (npm): vulnerable <= 2026.2.21-2, patched in 2026.2.22.
@openclaw/voice-call (npm): vulnerable <= 2026.2.21, patched in 2026.2.22.

Technical Details

Before this fix, the voice-call media-stream path upgraded sockets first and ran shouldAcceptStream() after a later start frame. This created a pre-auth window where remote clients could hold idle sockets without call/token validation.

Impact

Availability risk in deployments where the media-stream endpoint is reachable and streaming is enabled. Under sustained abuse, this could consume connection-related resources and degrade service for legitimate streams.

Remediation

The fix adds layered controls in the media-stream path:

strict pre-start timeout (close sockets that do not send a valid start frame quickly)
global pending-connection cap
per-IP pending-connection cap
total open media-stream connection cap
safer upgrade-path parsing in the webhook server
