    Out-of-bounds Read

    @openzeppelin/contracts-upgradeable is a Secure Smart Contract library for Solidity.

    Affected versions of this package are vulnerable to Out-of-bounds Read via the lastIndexOf function when the buffer is empty and the pos argument is not set to its maximum value. An attacker can cause the function to access memory outside the intended buffer, potentially resulting in unexpected behavior such as returning an invalid index or causing a revert, by supplying crafted arguments.

    How to fix Out-of-bounds Read?

    Upgrade @openzeppelin/contracts-upgradeable to version 5.4.0 or higher.
