CoinVoice has learned that, according to the latest market information, Bitcoin Core has announced that versions 30 and 30.1 have a serious vulnerability when migrating old (BDB format) wallets. In very rare cases, this could lead to all wallet files on the node being accidentally deleted. Without backups, this may result in permanent loss of funds. This issue only affects the legacy wallet migration process; regular usage and existing wallets are not affected. The official fix for this vulnerability will be included in version 30.2. Until then, please refrain from performing wallet migration operations.
