Published Sep 26, 2026CWE-346EPSS 0.11%

Overview

CVE-2026-100598 is a high-severity vulnerability. It was published on September 26, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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
