CVE-2023-47033Public exploitNetwork attack vector

Ether theft via transaction-state reentrancy

Published Jan 19, 2024 · Updated May 30, 2025

Reentrancy in MultiSigWallet at 0xF0C99 allows attackers to execute a confirmed transaction repeatedly through a malicious callback. The executeTransaction function calls an attacker-controlled destination, and a reentrant callback causes incorrect resetting of the transaction's executed flag. The attack requires a confirmed transaction targeting a malicious contract; repeated execution drains Ether from the wallet.
