ynab4
The package downloads a prebuilt Windows executable (Setup.exe) from web.archive.org rather than the original upstream host (classic.youneedabudget.com). While the Wayback Machine URL does encode the original URL and a specific timestamp, web.archive.org is not the canonical distribution channel for this binary. The archived copy could differ from the original, and the integrity check is only MD5 (weak, collision-prone). The binary is installed into /usr/share/ynab4 and executed via a wrapper script through Wine, meaning it runs as user code. This is a genuine supply-chain concern: a prebuilt proprietary Windows installer from a non-canonical mirror with only MD5 verification. However, there is no evidence of active malice — the original upstream URL is embedded in the archive URL, the software is a known commercial product (YNAB 4), and the pattern of archiving a discontinued installer is common for legacy software. The medium rating is appropriate: executed binary from a non-official host with weak integrity verification.
