Summary
- Ethereum developers patched a flaw in the upcoming Glamsterdam upgrade that could have allowed an operator to withdraw ETH intended for new validators.
- The vulnerability involved builder and validator deposits sharing a public key, potentially crediting both deposits to the builder and leaving staking services unable to recover their funds.
- No losses have been reported, and client teams must now incorporate the revised deposit rules before Glamsterdam can proceed toward a mainnet launch.
