Is this really a vulnerability in Cake Wallet? As far as I understand, the issue affects any wallet that connects to public Electrum servers. All you need to do to avoid falling for it is double-check the recipient addresses if you want to bump the transaction fee. That said, it's crucial to verify the full address, not just the last few characters.
This vulnerability affects all wallets that can connect to random servers using the Electrum protocol, so it applies to Cake as well. That said, it has already been fixed.
Meanwhile, the Cake developers continue their efforts to make improvements and fix bugs. Today, they dropped new release, namely,
version 6.5.2.
