Legacy Update 1.12.0 through 1.13.1 contains an origin validation error in the IsPermitted method of its ActiveX control. After successfully reading the hosting document's hostname, a hostname that is not on the permitted list falls through without setting E_ACCESSDENIED, causing IsPermitted to return S_OK. An attacker who induces a user to visit a malicious webpage in Internet Explorer can invoke the control to enumerate update and system information, install updates without consent, display dialogs, or restart the computer when a reboot is pending. This issue was fixed in Legacy Update 1.13.2.","state":0,"publishedAt":"2026-10-13T21:08:05.334+00:00","modifiedAt":"2026-10-17T00:50:41.672+00:00","affected":[{"ecosystem":"Vendor product","name":"LegacyUpdate","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"LegacyUpdate\",\n                    \"product\": \"LegacyUpdate\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.12.0, < 1.13.2\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/LegacyUpdate/LegacyUpdate/security/advisories/GHSA-f4g7-4gmx-jfgf","https://github.com/LegacyUpdate/LegacyUpdate/commit/7d62f0bfaa770d74cd6e2cb0bac9c1907df48033","https://github.com/LegacyUpdate/LegacyUpdate/commit/ae1c46c97f39a55a1937784d9f9beb30aa9147fd","https://github.com/LegacyUpdate/LegacyUpdate/releases/tag/v1.13.2.0","https://legacyupdate.net/news/2026/07/21/legacy-update-1-13-2"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-97381","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-97381","identifiers":["CVE-2026-97381"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
