According to DL News, the Ethereum Foundation awarded a $50,000 bug bounty to the security team Trust Security for identifying a 'high-severity' attack vector in ERC-4337 (Account Abstraction). This issue could be exploited to carry out 'censorship/harassment-style' attacks on account abstraction transactions (causing valid and correctly signed transactions to be maliciously rolled back and consume Gas). The Ethereum Foundation stated that the issue has been fixed in the latest version and recommends relevant protocols to upgrade as soon as possible. https://www.(wublock123.com)/index.php?m=content&c=index&a=show&catid=6&id=56277
