What is CVE-2026-100598?

CVE-2026-100598 is OpenClaw before 2026.7.1 Approval Binding Logic Error. The supplied enrichment data classifies it as Unclassified mapped to CWE-346 CWE-346.

Which versions are affected?

Affected product and version evidence is listed in the product table above. Current public advisories should be checked for exact version scope before patch targeting is finalized.

Is there active exploitation?

Active exploitation is not confirmed from current sources for CVE-2026-100598. If exploitation is not confirmed from current sources, teams should document that status and continue monitoring KEV, vendor, and telemetry updates.

No. CVE-2026-100598 is not listed in CISA KEV in the supplied enrichment data. KEV status should be monitored because it can change after initial disclosure or after exploitation becomes publicly confirmed.

Is there a public exploit?

2 public PoC repositories reported; 0 marked weaponized in current dataset. Public exploit or PoC availability should raise triage priority, especially for exposed or business-critical systems.

How can defenders detect it?

Start with web/proxy/WAF logs, application logs, network IDS/IPS where available. Look for vulnerability-class behavior, product errors, suspicious authentication events, exploit probes, and abnormal process activity based only on evidence that applies to the affected product.

How should teams prioritize it?

Prioritize CVE-2026-100598 using CVSS 7.1, EPSS 0%, KEV status, public PoC status, and asset exposure. Internet-facing, privileged, or business-critical deployments should be handled first.

Are workarounds available?

The supplied mitigation guidance says to apply vendor patches and restrict external exposure until fixed. Fixed-version evidence is listed in the mitigation section above.

Which threat actors are linked publicly?

No public threat actor linkage is confirmed from current sources. Do not attribute exploitation to a threat actor unless the source evidence explicitly supports that linkage.

What should be done in the next 24 hours?

Identify exposed assets running affected vendor/product/version combinations. Prioritize based on EPSS, PoC availability, and external exposure. Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class. Open remediation tickets with affected assets, owners, evidence status, and detection coverage so decisions are traceable.

CVE-2026-100598

CVE-2026-100598 — OpenClaw before 2026.7.1 Approval Binding Logic Error

OpenClaw (npm package openclaw) before 2026.7.1 incorrectly binds Signal approval reactions. In affected versions, a reaction intended to resolve a structured approval request could instead attach to ordinary outbound text when unrelated outbound messages and a pending approval are present in the same conversation. As a result, an approver's reaction to unrelated text could be interpreted as approving or denying a pending host action; the practical impact depends on the pending request, conversation timing, and the actions available to the OpenClaw process. The issue does not change the authority of correctly identified approvers. This is fixed in version 2026.7.1.

Remediation

The vendor's own words where we have them.

Upgrade OpenClaw to a fixed release (2026.7.1). Apply vendor patches per advisory and restrict external exposure of the affected component until patched.

Answered from this record1

What should defenders know first?

CVE-2026-100598 is OpenClaw before 2026.7.1 Approval Binding Logic Error, a high vulnerability affecting OpenClaw from OpenClaw. The current evidence does not list it in CISA KEV, and the exploit status is: Active exploitation is not confirmed from current sources for CVE-2026-100598. Public exploit evidence is: 2 public PoC repositories reported; 0 marked weaponized in current dataset. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 7.1 describes technical severity, while EPSS 0% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
