Summary: The Escrow.sol contract has been analyzed for common Solidity vulnerabilities. The analysis revealed a reentrancy attack potential during an external call and weak access control that could allow unauthorized access.

Vulnerability Details:

• Reentrancy Attack Potential: SWC-107: External call may lead to reentrancy.

  (bool sent, ) = recipient.call{value: amount}("");

  Line: 85

• Access Control: SWC-119: Weak access control.

  require(msg.sender == owner, "Unauthorized access");

  Line: 42

Impact: Unauthorized access to funds or manipulation of escrow contracts.

Tools Used: Manual code inspection.

Recommendations:

• Reentrancy Fix: Use ReentrancyGuard to prevent reentrancy attacks.

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

• Access Control Fix: Replace with OpenZeppelin Ownable for robust access control.

  import "@openzeppelin/contracts/access/Ownable.sol";

  require(msg.sender == owner(), "Unauthorized access");
