CVE-2026-100598: OpenClaw Signal approval reaction binding logic error

CVE-2026-100598 · Severity: high · CVSS 7.1 · Published 2026-09-26

OpenClaw is an npm package that manages approval workflows for host actions via Signal reactions. A logic error causes approval reactions to bind to unrelated text messages instead of the intended approval request, allowing an approver to accidentally approve or deny critical actions by reacting to a different message. The actual impact depends on what host actions are pending and the conversation context.

Technical details

The vulnerability is an origin validation error (CWE-346) in Signal approval reaction binding: when unrelated outbound messages and a pending approval coexist in the same conversation, a reaction meant for the approval request can attach to ordinary text instead. An attacker with ability to introduce unrelated messages into a conversation with an approver who holds authority could trigger unintended approvals or denials. The fix is to upgrade to version 2026.7.1 or later, which corrects the binding logic.
