transferfrom with arbitrary from address allows attackers to receive tokens in L2 without paying

Lines of code Vulnerability details Impact In , the line token.transferFromfrom, escrow, amount; use an arbitrary from address. So an attacker can deposit victim's GTR token on L1, by using from address as victim's address, and receive equivalent tokens on L2 on attacker address. Proof of Concept...

GHSA-9J3M-G383-29QR OpenZeppelin Contracts's Cross chain utilities for Arbitrum L2 see EOA calls as cross chain calls

Impact Contracts using the cross chain utilies for Arbitrum L2, CrossChainEnabledArbitrumL2 or LibArbitrumL2, will classify direct interactions of externally owned accounts EOAs as cross chain calls, even though they are not started on L1. This is assessed as low severity because any action taken...

Business Logic Flaws

OpenZeppelin Contracts has business logic flaws. The vulnerability exists due to a lack of sanitization between cross chains allowing contracts using Arbitrum L2, CrossChainEnabledArbitrumL2 or LibArbitrumL2 to be classified as direct interactions of externally owned accounts EOAs even though the...
