  "description": "7-Zip for Windows through 26.01 fails to preserve the Mark-of-the-Web when extracting a crafted RAR5 archive, because its guard that suppresses an archive-supplied Zone.Identifier stream matches the exact name \u0027Zone.Identifier\u0027 while a RAR5 STM record named \u0027:Zone.Identifier:$DATA\u0027 is not matched and NTFS canonicalizes it to the same stream, overwriting the propagated Internet-zone marker with ZoneId=0. A second STM record named \u0027::$DATA\u0027 overwrites the extracted file\u0027s default data stream, letting an attacker defeat SmartScreen/MotW warnings and spoof file content.",
