According to CoinDesk, the vulnerability was triggered when users attempted to accelerate payments, giving a malicious server the opportunity to steal funds.
The available report does not name the wallet, the number of affected users, the amount lost or whether a fix has been released.
The incident points to risks in client software that depends on remote servers, rather than to a flaw in the Bitcoin protocol.
