@openzeppelin/contracts@4.0.0-beta.1 vulnerabilities

@openzeppelin/contracts is a library for contract development.

Affected versions of this package are vulnerable to Denial of Service (DoS) such that a function in the implementation contract may be inaccessible if its selector clashes with one of the proxy's own selectors. Specifically, if the clashing function has a different signature with incompatible ABI encoding, the proxy could revert while attempting to decode the arguments from calldata.

Upgrade @openzeppelin/contracts to version 4.8.3 or higher.

@openzeppelin/contracts is a library for contract development.

Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature via ECDSA.recover and ECDSA.tryRecover due to accepting EIP-2098 compact signatures in addition to the traditional 65 byte signature format.

Upgrade @openzeppelin/contracts to version 4.7.3 or higher.

@openzeppelin/contracts is a library for contract development.

Affected versions of this package are vulnerable to Denial of Service (DoS) in the supportsERC165InterfaceUnchecked() function in ERC165Checker.sol and ERC165CheckerUpgradeable.sol, which can consume excessive resources when processing a large amount of data via an EIP-165 supportsInterface query.

Upgrade @openzeppelin/contracts to version 4.7.2 or higher.

@openzeppelin/contracts is a library for contract development.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data. It is possible for initializer() protected functions to be executed twice, if this happens in the same transaction. For this to happen, either one call has to be a subcall to the other, or both calls have to be subcalls of a common initializer() protected function. This can be particularly dangerous if the initialization is not part of the proxy construction, and reentrancy is possible by executing an external call to an untrusted address.

NOTE: This vulnerability has also been identified as: CVE-2021-46320

Upgrade @openzeppelin/contracts to version 4.4.1 or higher.

Upgrade @openzeppelin/contracts to version 4.4.1 or higher.

@openzeppelin/contracts is a library for contract development.

Affected versions of this package are vulnerable to Privilege Escalation. A vulnerability in TimelockController allowed an actor with the executor role to escalate privileges.

As a workaround, revoke the executor role from accounts not strictly under the team's control. It is recommended to revoke all executors that are not also proposers. When applying this mitigation, ensure there is at least one proposer and executor remaining.

Upgrade @openzeppelin/contracts to version 4.3.1, 3.4.2 or higher.
