That looks like you'd have to download and run a hacked installer that was never avaliable from an official location. That is a much lower risk than a supply-chain attack where anyone building birwarden-cli from the official repo would be infected via the compromised dependency.

Long term keepass users aren't going to be affected. If you mention software to others make sure you send them a link to a known safe download location instead of having them search for one (as new users searching like that are more at risk of stumbling on a malicious copy of the official site hosting a hacked version).
