Integer Overflow in Endian Library. Impact: Unexpected behavior in smart contract due to integer overflow vulnerability. Proof of Concept: 32-byte input value converted to 256-bit and then back to 64-bit, causing potential overflow. Attacker can exploit by submitting large input value. Tools Used: VSCODE. Recommended Mitigation: Update Endian library to handle input values larger than 64 bits or restrict input size
