Additionally, they should restrict access to voice call features and monitor for suspicious activity.

Why it matters

CVE-2026-100544 is a high-severity vulnerability in the @openclaw/voice-call package that allows remote callers to potentially access sensitive data, modify files, execute commands, or control connected services. Defenders should prioritize verifying and upgrading to version 2026.8.1 or later, and restrict access to voice call features.

• Potential unauthorized access to sensitive data
• Possible modification of files or execution of commands
• Potential control of connected services
• Verification of affected versions and configurations

Technical summary

The @openclaw/voice-call package before version 2026.8.1 launches the configured agent for classic inbound voice calls without propagating the caller's identity or non-owner status, potentially allowing remote callers to drive tools intended for the trusted owner. This authorization bypass vulnerability can lead to unauthorized access to sensitive data, modification of files, execution of commands, or control of connected services, depending on the agent's configuration. The issue is fixed in version 2026.8.1, and defenders should prioritize verifying and upgrading to this version or later.

Defensive priority

Defenders should prioritize verifying and upgrading to version 2026.8.1 or later, and restrict access to voice call features.

Recommended defensive actions

• Verify and upgrade to version 2026.8.1 or later
• Restrict access to voice call features
• Monitor for suspicious activity
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
