Reentrancy Guard:

While a reentrancy guard is mentioned in some comments, it's essential to ensure that all functions susceptible to reentrancy attacks have proper guards in place.

Here are examples of a vulnerable function without a reentrancy guard:

"function vulnerableFunction(uint256 poolId_, address user_) external {
// ... function logic ...

// Vulnerable to reentrancy attack if there are external calls or state changes below
// ..."

In this example, the function vulnerableFunction lacks a reentrancy guard. If there are any external calls or state changes within the function logic, it could be susceptible to reentrancy attacks. To mitigate this vulnerability, a reentrancy guard should be added. Here's an example of how might implement a simple reentrancy guard:
"ool private _locked;

function vulnerableFunction(uint256 poolId_, address user_) external {
require(!_locked, "Reentrancy guard");
_locked = true;

// ... function logic ...

// Safe from reentrancy attacks due to the guard

// ... more logic ...

_locked = false;

}"
