Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.11%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

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.
