Functions like deposit, redeem, and unstake perform external calls (e.g., safeTransferFrom, safeTransfer) without reentrancy guards, allowing attackers to re-enter and manipulate the contract state.

Vulnerability Details

1. Reentrancy Attack Risk

Code Affected:

All state-changing functions.

deposit(), redeem(), unstake()functions

Impact

• Potential fund theft due to malicious reentrancy attacks.

• Unauthorized state manipulation leading to financial losses.

Tools Used

• Manual Code Review: Identified lack of reentrancy protection.

• Slither: Detected potential reentrancy attack surfaces.

Recommendations

1. Implement reentrancy guards (e.g., nonReentrant from OpenZeppelin’s ReentrancyGuard).

2. Ensure external calls occur last in functions to prevent state inconsistencies.

3. Perform thorough testing with adversarial reentrancy simulations.
