Bitcoin Core 31.0's -privatebroadcast has a privacy vulnerability: when IPv4/IPv6 node handshake fails with BIP324 v2 enabled, it falls back to v1 direct connection, exposing the transaction originator's IP without Tor. Affected are nodes that enable -privatebroadcast and broadcast via sendrawtransaction, as well as nodes capable of outbound IPv4/IPv6 connections; wallet RPC, onion, and I2P are unaffected. The fix will be released with 31.1; it is recommended to disable -privatebroadcast, disable v2, or route outbound traffic through Tor before upgrading.
