Out-of-bounds Read

@openzeppelin/contracts and @openzeppelin/contracts-upgradeable are vulnerable to Out-of-bounds Read. The vulnerability is due to improper bounds checking caused by the lastIndexOf function in Bytes.sol accessing uninitialized memory when given an empty buffer and a non-maximum position,...

CVE-2025-54070

OpenZeppelin Contracts is a library for secure smart contract development. Starting in version 5.2.0 and prior to version 5.4.0, the lastIndexOfbytes,byte,uint256 function of the Bytes.sol library may access uninitialized memory when the following two conditions hold: 1 the provided buffer length...

GHSA-9RCW-C2F9-2J55 OpenZeppelin Contracts Bytes's lastIndexOf function with position argument performs out-of-bound memory access on empty buffers

Impact The lastIndexOfbytes,byte,uint256 function of the Bytes.sol library may access uninitialized memory when the following two conditions hold: 1 the provided buffer length is empty i.e. buffer.length == 0 and position is not 2256 - 1 i.e. pos != typeuint256.max. The pos argument could be used...

CVE-2025-54070

OpenZeppelin Contracts (Bytes.sol) lastIndexOf(bytes, byte, uint256) is vulnerable in versions prior to 5.4.0 when the input buffer is empty (buffer.length == 0) and pos != type(uint256).max. In this scenario, the function may access uninitialized memory at buffer + 0x20 + pos, potentially return...

CVE-2024-45304

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 where an unintend...

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...

CVE-2023-30542

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 elements of the latter to be...
