Call Code vulnerabilities

How Calls work

When contract A makes a call to another contract B by calling a function, the execution of said function relies on contract B's storage, while msg.sender is contract A.

Here's a table showing the context of the calls, with an EOA initiating the whole sequence.

	Contract A	Contract B
msg.sender	EOA address	Contract A address
msg.value	EOA send value	Contract A send value
storage	Contract A	Contract B
