I found a critical vulnerability that affects all monero wallets. they display the transaction amount on the user's computer screen. this will leak information about how much cocaine the user buys if the chupacabra sneaks up behind them and looks at the screen.
I disclosed the vulnerability to the featherwallet developers and they have been ignoring it for 8 months!
none of the lightning wallets are affected by this vulnerability because you cannot use lightning to buy cocaine anywhere.
