{"schema":"threatline.record/2","record":{"id":"CVE-2026-14765","aliases":[],"summary":"Epic Games Unreal Engine Insecure Default URL Scheme Allowance in LaunchURL","details":"Epic Games Unreal Engine versions up to and including 5.8.0 ship with an insecure default configuration for the LaunchURL Blueprint node (UKismetSystemLibrary::LaunchURL). 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).","categories":["Unclassified"],"product":"Unreal Engine","vendor":"Epic Games","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-14765","source_modified_at":"2026-10-18T13:54:09.144Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Unreal Engine","vendor":"Epic Games","versions":[{"status":"affected","version":"0","lessThanOrEqual":"5.8.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":7.7,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00387,"percentile":0.31572,"score_date":"2026-10-23"},"published_at":"2026-10-14T02:31:08.607Z","modified_at":"2026-10-18T13:54:09.144Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-14765","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-18T13:54:09.144Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-14765","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://khaelkugler.com/blogs/meccha_chameleon.html","tags":["related"]},{"source":"CVE List","url":"https://takeonme.org/gcves/GCVE-1337-2026-00000000000000000000000000000000000000000000000001011111111101111111111110000000000000000000000000000000000000000000000000000001011","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"total","assessed_at":"2026-10-18T13:29:54.607074Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-18T13:54:09.144Z","content_hash":"584ff4916fd5319c254d90c11b8c2f91abd6387b827841867e54af8cd1922fae"}}
