Summary

The Starklane contract lacks a storage gap, which poses a risk of storage conflicts in future upgrades. This could lead to unintended overwriting of state variables, compromising the contract's integrity and functionality.

Vulnerability Details

The contract does not include a storage gap, which is necessary for upgradeable contracts to prevent storage layout conflicts when new state variables are added.

The end of the contract's state variable declarations does not have a reserved storage gap.

Impact

Without a storage gap:

Future upgrades that introduce new state variables may overwrite existing ones, leading to unpredictable behavior or loss of critical data.

The absence of a storage gap undermines the upgradeability and safety mechanisms, potentially causing operational disruptions.

Recommendations

Introduce a reserved storage gap at the end of the state variable declarations to safeguard against future upgrades.
