{"id":"CVE-2026-100598","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-100598","generatedAt":"2026-10-28T02:59:12.500Z","title":"OpenClaw (npm package openclaw) before 2026.7.1 incorrectly binds Signal approval reactions.","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.","published":"2026-09-26T03:17:08.000Z","lastModified":"2026-09-28T20:17:08.000Z","status":"Deferred","sourceIdentifier":"disclosure@vulncheck.com","cvss":{"version":"4.0","score":7.5,"severity":"HIGH","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-346"],"affected":[],"epss":{"score":0.00114,"percentile":0.01495,"date":"2026-10-26","history":[{"date":"2026-09-26","score":0.00114,"percentile":0.01354}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.11%).
