8 Low
Critical

Reentrancy in withdraw()

External call to msg.sender before balance update allows recursive invocation to drain funds.

✓ Apply checks-effects-interactions pattern
High

Unprotected setOwner()

Missing access control allows any caller to change contract ownership.

✓ Add onlyOwner modifier to setOwner
Medium

Unchecked external call return value

Transfer return value is not checked; silent failures may leave funds locked.

✓ Use require() to validate transfer success
