ECHO-A273-202B-9560 Windows-only. The flaw is that 7-Zip for Windows fails to preserve the Mark-of-the-Web when extracting a crafted RAR5 archive, because a RAR5 STM record named ':Zone.Identifier:$DATA' / '::$DATA' is canonicalized by NTFS transparent Alternate Data Streams to overwrite the propagated Internet-zone marker / default data stream, defeating SmartScreen/MotW. MotW, Zone.Identifier ADS and NTFS :$DATA canonicalization do not exist on Linux (ntfs-3g does not do transparent ADS canonicalization), so the Echo Linux build is not affected. Debian marks trixie <ignored> for the same reason.
