## [M-07] ERC20 return values not checked

Lines of code Vulnerability details Impact Tokens that don’t actually perform the transfer and return false are still counted as a correct transfer and the tokens remain in the SingleNativeTokenExitV2 contract and could potentially be stolen by someone else. Proof of Concept The ERC20.transfer an...

Signature malleability not protected against

Lines of code Vulnerability details Impact A signature should never be included into a signed message hash to check if previously messages have been processed by the contract. See reference: Proof of Concept Provide direct links to all referenced code in GitHub. Add screenshots, logs, or any othe...

[MEDIUM] ARCDVestingVault#deposit and NFTBoostVault#_lockTokens- Unsafe transferFrom function is not properly invoked

Lines of code Vulnerability details Impact The use of transferFrom in the ARCDVestingVaultdeposit and NFTBoostVaultlockTokens functions presents a risk of erroneous token transfers. The transferFrom function doesn't perform necessary validations e.g. validate the returned bool in case of failure,...

StandardizedToken can be setup multiple times by anyone. Causing unlimited mint by anyone.

Lines of code Vulnerability details Impact StandardizedToken can be setup multiple times by anyone. Causing unlimited mint by anyone. Proof of Concept function setupbytes calldata params external override onlyProxy address distributor; address tokenManager; string memory tokenName; tokenManager,...

Collateralization ratio manipulation can cause a denial of service

Lines of code Vulnerability details Impact Stablecoin redeeming and profit accruing in the SavingsVest contract can be blocked when the collateralization ratio has overflown. Proof of Concept The mitigation recommended in 31 and implemented by the sponsor in this commit doesn't resolve the root...

Users with DEPLOY permission can grief each other through CREATE2

Lines of code Vulnerability details Bug Description In ERC725XCore.sol, the deployCreate2 function uses Openzeppelin's Create2.deploy to deploy new contracts: ERC725XCore.solL253-L267 function deployCreate2 uint256 value, bytes memory creationCode internal virtual returns bytes memory newContract...

cancelSig will not completely cancel signatures due to malleability vulnerabilities

Lines of code Vulnerability details Impact The current version of openzeppelin contracts has a high risk of vulnerability about signature malleability attack: OpenZeppelin/openzeppelin-contracts3610. So if the signer only cancel one signature, the malicious proposer can still extend a fully valid...

ERC721 onERC721Received() reentrancy

Lines of code Vulnerability details Impact Reentrancy is an attack that can occur when a bug in a contract may allow a malicious contract to reenter the contract unexpectedly during execution of the original function. This can be used to drain funds from a smart contract if used maliciously...

In MulticallRootRouter.sol, approve function can fail for non standard ERC20 tokens like USDT

Lines of code Vulnerability details Impact Some tokens like USDT do not work when changing the allowance from an existing non-zero allowance value. For example Tether USDT’s approve function will revert if the current approval is not zero, to protect against front-running changes of approvals. Li...

Voting Delay set to 1 block, would not allow users enough time to buy tokens, or delegate their votes before the voting starts

Lines of code Vulnerability details Impact Detailed description of the impact of this finding. With a voting delay set to 1 block, users would not have enough time to buy tokens, or delegate their votes. Proof of Concept Provide direct links to all referenced code in GitHub. Add screenshots, logs...

OpenZeppelin Contracts using MerkleProof multiproofs may allow proving arbitrary leaves for specific trees

Impact When the verifyMultiProof, verifyMultiProofCalldata, processMultiProof, or processMultiProofCalldata functions are in use, it is possible to construct merkle trees that allow forging a valid multiproof for an arbitrary set of leaves. A contract may be vulnerable if it uses multiproofs for...
