Summary: Analyzed for common Solidity vulnerabilities related to collection management.

Vulnerability Details:

• Reentrancy Attack Potential: SWC-107: External calls in functions handling collection operations could be vulnerable.
  Severity: Medium

  (bool success, ) = collection.call{value: amount}("");

  Line: 76

• Unchecked Arithmetic: SWC-101: Operations on collection balances may cause overflows.
  Severity: Medium

  uint256 newBalance = currentBalance - withdrawalAmount;

  Line: 89

Impact: Could lead to unauthorized collection manipulation, incorrect balances, or fund loss.

Tools Used: Manual code inspection.

Recommendations:

• Reentrancy Fix: Use ReentrancyGuard to prevent reentrancy attacks.

  import "@openzeppelin/contracts/security/ReentrancyGuard.sol";

• Arithmetic Fix: Use safe math operations to prevent overflows and underflows.

  uint256 newBalance = SafeMath.sub(currentBalance, withdrawalAmount);
