from 6th May to today (12th May) the AppImage and Ubuntu zip assets of Cemu 2.6 on our github were compromised by a pro-Russian threat actor.
If you are a Windows or MacOS user you are not affected. If you are a flatpak user you are also not affected.

If you updated only before May you are not affected. No need to do anything.
