This flaw, dubbed "evilReflex," allows attackers to steal assets by exploiting unverified callcode, enabling unauthorized transfers of the contract's balances. The vulnerability is rated as HIGH severity (CVSS 7.5), indicating a network-based attack with low complexity and high impact on integrity, as attackers can directly manipulate asset transfers.
