Summary

A vulnerability was identified in the handling of the newOwners[] array within the Request structure.
The array is defined as uint256[], but it should be of type felt252[] to accurately represent Starknet addresses,
which are uint252. This discrepancy can lead to potential issues in the handling of addresses on Starknet,

Vulnerability Details

The newOwners[] array is currently defined as an uint256[], which is incompatible with Starknet's address format.
Starknet addresses are represented as felt252, which corresponds to uint252. The use of uint256 instead of felt252
may lead to data type mismatches, resulting in potential errors during execution, especially when interfacing with
Starknet contracts.

Impact

This vulnerability can lead to incorrect processing of address data on Starknet, potentially causing failures in cross-chain operations.
This may result in losses of assets when transferred to starknet.

Recommendations

Update the newOwners[] array in the Request structure to be of type felt252[] to ensure compatibility with Starknet addresses.
