7-Zip for Windows through 26.02 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 Zone.Identifier while a RAR5 STM record named :Zone.Identifier:$DATA is not matched and NTFS canonicalizes it to the same stream, overwriting the propagated Internet-zone marker with ZoneId=0. A second STM record named ::$DATA overwrites the extracted files default data stream, letting an attacker defeat SmartScreen/MotW warnings and spoof file content.
