An unauthenticated or public caller in WEB, API, TWITTER, or TELEGRAM contexts can exploit this by supplying the exact de-advertised tool name and arguments via indirect prompt injection or by replaying checkpoint and history data on a reused thread, achieving unauthorized execution of owner-restricted capabilities.","published":"2026-10-15T02:20:15.603","modified":"2026-10-15T02:20:15.603","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://www.lasso.security/vulnerability-database/cve-2026-76066"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/intentkit-executor-tool-authorization-bypass-via-toolnode"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-10-15T02:20:15.603"}}
