Critical Bug Alert Bitcoin Core Wallet Migration Failure Risks Deleting Unrelate

[God Tim]

NOTICE: Wallet Migration bug present in Bitcoin Core wallet 30.0 & 30.1.

Under rare circumstances, migrating a legacy (BDB) wallet can delete all wallet files on the same node. If those wallets aren't backed up, this can result in a loss of funds.

A fix will become available in Bitcoin Core 30.2. Until that is released, do not migrate legacy wallets using 30.0 or 30.1.

Well I noticed and saw a post on X that said this and  recently they disclosed bug in Bitcoin Core's wallet migration process poses a significant risk to users, potentially leading to the deletion of unrelated wallet files. This issue highlights the importance of exercising caution when managing Bitcoin wallets and staying informed about software vulnerabilities.

Note:Only the legacy wallet migration process is affected. All other uses are unaffected. You can continue using Bitcoin Core normally, including existing wallets and running a node without wallets.
