UNCX suffered a contract vulnerability attack, resulting in a loss of approximately $86000

SlowMist revealed that UNCX was attacked due to a vulnerability in the contract function VestingManager. cancel (uint256), resulting in a loss of approximately $86000. The attacker lowered the conversion rate by transferring tokens to the management contract and cancelled the plan to release shares, resulting in an excessive reduction of global shares and the withdrawal of excess tokens from the shared pool.
