CVE-2022-31170

OpenZeppelin Contracts is a library for smart contract development. Versions 4.0.0 until 4.7.1 are vulnerable to ERC165Checker reverting instead of returning false. ERC165Checker.supportsInterface is designed to always successfully return a boolean, and under no circumstance revert. However, an...

CVE-2022-31172

OpenZeppelin Contracts is a library for smart contract development. Versions 4.1.0 until 4.7.1 are vulnerable to the SignatureChecker reverting. SignatureChecker.isValidSignatureNow is not expected to revert. However, an incorrect assumption about Solidity 0.8's abi.decode allows some cases to...

CVE-2024-27094

OpenZeppelin Contracts is a library for secure smart contract development. The Base64.encode function encodes a bytes input by iterating over it in chunks of 3 bytes. When this input is not a multiple of 3, the last iteration may read parts of the memory that are beyond the input buffer. The...

OpenZeppelin Contracts vulnerable to Improper Escaping of Output

Impact OpenZeppelin Contracts is a library for secure smart contract development. Starting in version 4.0.0 and prior to version 4.9.3, contracts using ERC2771Context along with a custom trusted forwarder may see msgSender return address0 in calls that originate from the forwarder with calldata...

CVE-2023-34459

OpenZeppelin Contracts (versions 4.7.0–4.9.1) are affected by a multiproof forgery issue when using verifyMultiProof/verifyMultiProofCalldata/processMultiProof/processMultiProofCalldata. If the merkle tree includes a node with value 0 at depth 1 under the root, a adversarial or certain benign tre...

CVE-2023-34234

OpenZeppelin Contracts’ Governor-related vulnerability (CVE-2023-34234) allows an attacker to frontrun the creation of a proposal, enabling the attacker to become the proposer and repeatedly cancel proposals. Affected: Governor (v4.9.0) and GovernorCompatibilityBravo (since v4.3.0). Root cause: l...

CVE-2023-30541 TransparentUpgradeableProxy clashing selector calls may not be delegated in @openzeppelin/contracts

OpenZeppelin Contracts is a library for secure smart contract development. 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,...
