Ethereum patches Glamsterdam bug that could redirect staking deposits to builders

Ethereum developers fixed a vulnerability in the upcoming Glamsterdam upgrade that could have allowed operators to withdraw ETH intended for new validators. The bug stemmed from builder and validator deposits sharing a public key, which risked crediting both deposits to the builder and leaving staking services unable to recover funds. The fix, merged on October 27, ensures pending deposits are sorted by withdrawal credentials, keeping validator deposits separate from builder deposits.
