    Integer Overflow or Wraparound

    @openzeppelin/confidential-contracts is a Smart Contract library for use with confidential coprocessors

    Affected versions of this package are vulnerable to Integer Overflow or Wraparound in the wrap and onTransferReceived functions used by the ERC7984 contract. An attacker can cause users to lose funds by triggering a silent failure in the _mint function, resulting in the underlying tokens being sent without receiving the corresponding confidential wrapped tokens. By default, this overflow happens after wrapping ~18.4 trillion tokens.

    How to fix Integer Overflow or Wraparound?

    Upgrade @openzeppelin/confidential-contracts to version 0.3.1 or higher.
