The vulnerability affects the KeePass 2.X branch for Windows, and possibly for Linux and macOS. It has been fixed in the test versions of KeePass v2.54 – the official release is expected by July 2023. It’s unfortunate that the PoC tool is already publicly available and the release of the new version so far off, but the risk of CVE-2023-32784 being abused in the wild is likely to be pretty low, according to the researcher.
Bitwarden is also FLOSS and self-hostable. As much as I love KeePassXC, using it for team passwords is a pain. Having a self-hosted Bitwarden thingy would be way better.
