High Severity Issues

No issues

Medium Severity Issues
----------------------
No issues

Low Severity Issues
-------------------
Title:       Compiler Bug - EventStructWrongData
Description: The version pragma, >0.4.22, can be satisfied by a version of the Solidity compiler that contains a known bug. If a struct is used in an event, the address of the struct is logged instead of the actual data. This bug is reported to be fixed in version 0.5.0.

Informational Severity Issues
-----------------------------
Title:       Default Function Visibility
Description: No visibility is specified for function transfer(address to, uint amount) in contract Vulnerable. The default is public. It should be confirmed that this is desired, and the visibility of the function should be explicitly set.

Title:       Default Function Visibility
Description: No visibility is specified for function withdraw() in contract Vulnerable. The default is public. It should be confirmed that this is desired, and the visibility of the function should be explicitly set.
