In CollateralizedDebt.sol, the mint() function calls _safeMint() which has a callback to the to address argument.  Functions with callbacks should have reentrancy guards in place for protection against possible malicious actors both from inside and outside the protocol.
Add a reentrancy guard modifier on the mint() function in CollateralizedDebt.sol
