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.","state":0,"publishedAt":"2026-10-15T01:39:56.474+00:00","modifiedAt":"2026-10-22T16:32:28.459+00:00","affected":[{"ecosystem":"Vendor product","name":"intentkit","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unknown\",\n                    \"vendor\": \"crestalnetwork\",\n                    \"product\": \"intentkit\",\n                    \"packageURL\": \"pkg:github/crestalnetwork/intentkit\",\n                    \"repo\": \"https://github.com/crestalnetwork/intentkit\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"semver\",\n                            \"lessThanOrEqual\": \"2.6.3\"\n                        },\n                        {\n                            \"status\": \"unaffected\",\n                            \"version\": \"5b91da5734d1ac16cd656fa66a86caf8f15cd671\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N","score":8.7,"severity":"HIGH"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","score":7.5,"severity":"HIGH"}],"references":["https://www.lasso.security/vulnerability-database/cve-2026-76066","https://github.com/crestalnetwork/intentkit/commit/5b91da5734d1ac16cd656fa66a86caf8f15cd671","https://www.vulncheck.com/advisories/intentkit-executor-tool-authorization-bypass-via-toolnode"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-76066","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-76066","identifiers":["CVE-2026-76066"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
