Bitcoin Core: Vulnerability Exists in Old Wallet Migration for Versions 30.0 and 30.1

According to Techub News, the Bitcoin Core Project posted on X that in rare cases during the migration process of older (BDB) wallets using Bitcoin Core 30.0 and 30.1, all wallet files on the same node may be deleted, potentially leading to fund loss if not backed up. A fix will be released with Bitcoin Core 30.2, and it is not recommended to use 30.0 or 30.1 for old wallet migrations until then. Aside from the migration process, other functions remain unaffected; node operation and existing wallets will continue to function normally.
