Description
openclaw's @openclaw/voice-call package before 2026.8.1 launches the configured agent for classic inbound voice calls without propagating the caller's identity or non-owner status. As a result, owner-only tool filtering can fail open and expose the agent's normal tool authority to a remote caller. A caller who is admitted by the configured inbound-call policy (open, pairing, or allowlist) on a deployment with inbound calling enabled can therefore drive tools intended for the trusted owner, potentially reading data, modifying files, executing commands, or controlling connected services depending on the agent's configuration. The issue is fixed in 2026.8.1.
Detection & mitigation playbook
VulnerabilityDetect
Identify every host running the affected component and compare the installed build against the fixed version below — for source-built or distro-packaged software the version string, not a lockfile, is the source of truth (`dpkg -l`, `rpm -q`, or the binary's own `--version`). Because exploitation targets the running service rather than your application code, O3 also flags the exploit behaviour from runtime telemetry and egress traffic.
Remediation status
No fixed release is recorded for CVE-2026-100544 yet. Track the upstream advisory, and apply the exposure-reduction steps below in the meantime.
Mitigate without a patch
Reduce reachability while you patch: restrict network access to the service to trusted sources, disable or gate the affected component where your deployment allows it, and add a WAF/IPS signature if one exists for CVE-2026-100544. O3's runtime protection blocks the cwe-862 flaw at execution, which holds the line on hosts you cannot patch immediately.
How O3 protects you
O3 detects and blocks CVE-2026-100544 exploitation at runtime with eBPF exploit-chain detection, plus L7 egress monitoring that catches a post-exploitation callback and cuts the attacker's outbound channel.
Tailored to CVE-2026-100544. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
