According to a report by Jinse Finance, BlockSec Phalcon has issued a warning that its system has detected a "transferFrom" issue, resulting in a loss of approximately $90,000 on the Base chain. This problem is caused by insufficient access control, which allows arbitrary low-level calls in the callback function. It is recommended to immediately revoke all approvals for the unknown contract 0xD9f4a3238154ff6439e37F98c9B11489353715Bb.
