| CVE-2018-13542 | Hig | 0.49 | 7.5 | 0.01 | Jul 9, 2018 | The mintToken function of a smart contract implementation for ZIBToken, an Ethereum token, has an integer overflow that allows the owner of the contract to set the balance of an arbitrary user to any value. | ||
| CVE-2025-54070 | Med | 0.38 | — | 0.00 | Jul 17, 2025 | OpenZeppelin Contracts is a library for secure smart contract development. Starting in version 5.2.0 and prior to version 5.4.0, the `lastIndexOf(bytes,byte,uint256)` function of the `Bytes.sol` library may access uninitialized memory when the following two conditions hold: 1)… | ||
| CVE-2024-45304 | 0.00 | — | 0.00 | Aug 30, 2024 | Cairo-Contracts are OpenZeppelin Contracts written in Cairo for Starknet, a decentralized ZK Rollup. This vulnerability can lead to unauthorized ownership transfer, contrary to the original owner's intention of leaving the contract without an owner. It introduces a security risk… | |||
| CVE-2024-27094 | 0.00 | — | 0.01 | Feb 29, 2024 | 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… | |||
| CVE-2023-49798 | 0.00 | — | 0.01 | Dec 8, 2023 | OpenZeppelin Contracts is a library for smart contract development. A merge issue when porting the 5.0.1 patch to the 4.9 branch caused a line duplication. In the version of `Multicall.sol` released in `@openzeppelin/contracts@4.9.4` and `@openzeppelin/contracts-upgradeable@4.9.4… | |||
| CVE-2023-40014 | 0.00 | — | 0.01 | Aug 10, 2023 | 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 `address(0)` in calls that originate from the… | |||
| CVE-2023-34459 | 0.00 | — | 0.00 | Jun 16, 2023 | OpenZeppelin Contracts is a library for smart contract development. Starting in version 4.7.0 and prior to version 4.9.2, when the `verifyMultiProof`, `verifyMultiProofCalldata`, `procesprocessMultiProof`, or `processMultiProofCalldat` functions are in use, it is possible to… | |||
| CVE-2023-34234 | 0.00 | — | 0.01 | Jun 7, 2023 | OpenZeppelin Contracts is a library for smart contract development. By frontrunning the creation of a proposal, an attacker can become the proposer and gain the ability to cancel it. The attacker can do this repeatedly to try to prevent a proposal from being proposed at all.… | |||
| CVE-2023-30541 | 0.00 | — | 0.01 | Apr 17, 2023 | 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… | |||
| CVE-2023-30542 | 0.00 | — | 0.01 | Apr 16, 2023 | OpenZeppelin Contracts is a library for secure smart contract development. The proposal creation entrypoint (`propose`) in `GovernorCompatibilityBravo` allows the creation of proposals with a `signatures` array shorter than the `calldatas` array. This causes the additional… | |||
| CVE-2023-26488 | 0.00 | — | 0.01 | Mar 3, 2023 | OpenZeppelin Contracts is a library for secure smart contract development. The ERC721Consecutive contract designed for minting NFTs in batches does not update balances when a batch has size 1 and consists of a single token. Subsequent transfers from the receiver of that token… | |||
| CVE-2022-39384 | 0.00 | — | 0.00 | Nov 4, 2022 | OpenZeppelin Contracts is a library for secure smart contract development. Before version 4.4.1 but after 3.2.0, initializer functions that are invoked separate from contract creation (the most prominent example being minimal proxies) may be reentered if they make an untrusted… | |||
| CVE-2022-35961 | 0.00 | — | 0.00 | Aug 14, 2022 | 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… | |||
| CVE-2022-35915 | 0.00 | — | 0.01 | Aug 1, 2022 | OpenZeppelin Contracts is a library for secure smart contract development. The target contract of an EIP-165 `supportsInterface` query can cause unbounded gas consumption by returning a lot of data, while it is generally assumed that this operation has a bounded cost. The issue… | |||
| CVE-2022-35916 | 0.00 | — | 0.00 | Aug 1, 2022 | OpenZeppelin Contracts is a library for secure smart contract development. Contracts using the cross chain utilities for Arbitrum L2, `CrossChainEnabledArbitrumL2` or `LibArbitrumL2`, will classify direct interactions of externally owned accounts (EOAs) as cross chain calls,… | |||
| CVE-2022-31198 | 0.00 | — | 0.01 | Aug 1, 2022 | OpenZeppelin Contracts is a library for secure smart contract development.

In affected… | |||
| CVE-2022-31170 | 0.00 | — | 0.01 | Jul 21, 2022 | 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… | |||
| CVE-2022-31172 | 0.00 | — | 0.00 | Jul 21, 2022 | 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`… | |||
