Wallet developer Electrum has released an emergency patch for a key vulnerability in bitcoin wallets. The vulnerability makes it possible for any website hosting an e-wallet to steal a user's cryptocurrency. The vulnerability means that in the JSONRPC interface, the password is exposed, implying that the hacker has full control of the wallet. However, the first patch failed to resolve the issue, forcing Electrum to release a second update on Sunday night.
