The URL scheme filter (FURLRequestFilter) is empty by default, which permits all URL schemes. On Windows, this results in a call to ShellExecuteW() with the open verb, so a supplied file:/// URI causes the referenced file to be executed. Any Unreal Engine game that loads user-generated content containing Blueprints is vulnerable to command execution via a malicious local file or a remote file on a WebDAV share. This is an instance of CWE-1188 (Initialization of a Resource with an Insecure Default).","state":0,"publishedAt":"2026-10-14T02:31:08.607+00:00","modifiedAt":"2026-10-18T13:54:09.144+00:00","affected":[{"ecosystem":"Vendor product","name":"Unreal Engine","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"Epic Games\",\n                    \"product\": \"Unreal Engine\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"lessThanOrEqual\": \"5.8.0\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","score":7.7,"severity":"HIGH"}],"references":["https://khaelkugler.com/blogs/meccha_chameleon.html","https://takeonme.org/gcves/GCVE-1337-2026-00000000000000000000000000000000000000000000000001011111111101111111111110000000000000000000000000000000000000000000000000000001011"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-14765","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-14765","identifiers":["CVE-2026-14765"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
