OpenZeppelin Contracts's GovernorVotesQuorumFraction updates to quorum may affect past defeated proposals

Impact This issue concerns instances of Governor that use the module GovernorVotesQuorumFraction, a mechanism that determines quorum requirements as a percentage of the voting token's total supply. In affected instances, when a proposal is passed to lower the quorum requirement, past proposals ma...

Not calling approve(0) before setting a new approval might cause reverts when used with Tether (USDT)

Lines of code Vulnerability details Impact Some tokens do not implement the ERC20 standard properly but are still accepted by most code that accepts ERC20 tokens. For example Tether USDT's approve function will revert if the current approval is not zero, to protect against front-running changes o...

Authorization Bypass

OpenZeppelin contracts are vulnerable to authorization bypass. The vulnerability is due to functions ECDSA.recover and ECDSA.tryRecover accepting EIP-2098 and 65-byte signatures. Affected contracts have signature reuse or replay protection, implemented by marking the signature as used rather than...

CVE-2022-35961

OpenZeppelin Contracts is a library for secure smart contract development. The functions ECDSA.recover and ECDSA.tryRecover are vulnerable to a kind of signature malleability due to accepting EIP-2098 compact signatures in addition to the traditional 65 byte signature format. This is only an issu...

FETH.sol is susceptible to ERC20 approve functionality front-running exploit

Lines of code Vulnerability details Proof of concept The problem is perfectly described here The tldr; is that if you approved a person to spend 100 tokens and then you want to decrease his allowance to 50, if he spends his 100 tokens allowance before you set his allowance to 50 he will be able t...

_safeMint() should be used rather than _mint() wherever possible

Lines of code Vulnerability details safeMint should be used rather than mint wherever possible Impact In NFTCollections.sol and NFTDropCollection, eventually it is called ERC721 mint. Calling mint this way does not ensure that the receiver of the NFT is able to accept them, making possible to los...

[H1] Protocol is unusable with some ERC20 tokens

Lines of code Vulnerability details Impact ​ Protocol unusable for USDT and other bad tokens Proof of Concept ​ Some ERC20 tokens do not implement correctly EIP-20 standard. They just do not return a boolean in transfer/transferFrom functions and just return void. Asking them for a boolean will...

Unsafe use of transfer()/transferFrom() with IERC20

Lines of code Vulnerability details Impact Some tokens do not implement the ERC20 standard properly but are still accepted by most code that accepts ERC20 tokens. For example Tether USDT's transfer and transferFrom functions do not return booleans as the specification requires, and instead have n...

createLock: User can lose funds by sending a wrong _value parameter

Lines of code Vulnerability details Impact Users can lose funds by sending a wrong value parameter. The problems relays in casting value to int128. Solidity does not check casting, just math operations. If a user tries to lock an amount greater than 2^128, the transaction won't be reverted and...

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...
