WEAPN keycode overwrites MONEY dependency in Laundrette::configureDependencies causing a bad migration
Summary
WEAPN keycode overwrites MONEY dependency in Laundrette::configureDependencies causing a bad migration.
Vulnerability Details
In case of of migration, owner will run the EmergencyMigration script that will call migrate(), that will call the kernel's executeAction(Actions.UpgradeModule, address(moneyVault)); with the kernel executor set as the caller, that will call _upgradeModule(Module newModule_) that will call _reconfigurePolicies(keycode); that will call configureDependencies() and here's the issue:
function configureDependencies() external override onlyKernel returns (Keycode[] memory dependencies) {
dependencies = new Keycode[](2);
dependencies[0] = toKeycode("MONEY");
moneyShelf = MoneyShelf(getModuleAddress(toKeycode("MONEY")));
dependencies[0] = toKeycode("WEAPN"); /// @audit here's the issue: overwriting dependencies[0], should be dependencies[1] instead
weaponShelf = WeaponShelf(getModuleAddress(toKeycode("WEAPN")));
}
Impact
Bad migration
Tools Used

Recommendations
- dependencies[0] = toKeycode("WEAPN");
+ dependencies[1] = toKeycode("WEAPN");
