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).","dates":{"published":"2026-10-14T02:31:08.607Z","modified":"2026-10-18T13:54:09.144Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":7.7,"severity":"high","version":"3.1","versionLabel":"v3.1","source":"CVE.org","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","computed":false,"selection":"backend-summary"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"CVE.org","score":7.7,"severity":"high","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"NVD","score":7.7,"severity":"high","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false},{"version":"3.1","versionLabel":"v3.1","source":"gcve","score":7.7,"severity":"high","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":0.00387,"percentile":0.31265,"severity":"low","asOf":"2026-10-19T00:00:00.000Z","change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[{"date":"2026-10-14T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00387,"percentile":0.31265}],"last30":[{"date":"2026-10-14T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-15T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-16T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-17T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-18T00:00:00.000Z","score":0.00387,"percentile":null},{"date":"2026-10-19T00:00:00.000Z","score":0.00387,"percentile":0.31265}]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-1188","name":"Initialization of a Resource with an Insecure Default","description":"The product initializes or sets a resource with a default that is intended to be changed by the product's installer, administrator, or maintainer, but the default is not secure.","type":"weakness","status":"Incomplete","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/1188.html"}],"affected":[{"vendor":"epic games","product":"unreal engine","name":"Unreal Engine","label":"unreal engine","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"≤ 5.8.0","noFixRecorded":false,"fixedIn":null}],"versionsText":"≤ 5.8.0","eol":null,"hubHref":"/vendor/epic_games/unreal_engine"}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://khaelkugler.com/blogs/meccha_chameleon.html","label":"khaelkugler.com/blogs/meccha_chameleon.html","hostname":"khaelkugler.com","tags":["Related"]},{"url":"https://takeonme.org/gcves/GCVE-1337-2026-00000000000000000000000000000000000000000000000001011111111101111111111110000000000000000000000000000000000000000000000000000001011","label":"takeonme.org/gcves/…","hostname":"takeonme.org","tags":["Third Party Advisory"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-14T02:31:08.607Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-10-18T13:54:09.144Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":31,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T13:09:58.753Z","stale":false,"partial":false}}
