CVE-2024-45304 OwnableTwoStep allows a pending owner to accept ownership after the original owner has renounced ownership in cairo-contracts

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...

OpenZeppelin Contracts for Cairo 安全漏洞

OpenZeppelin Contracts for Cairo is a secure smart contract development library open-sourced by OpenZeppelin. A security vulnerability exists in OpenZeppelin Contracts for Cairo versions prior to 0.15.1, which stems from an unauthorized ownership transfer mechanism that could result in an...

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 安全漏洞

OpenZeppelin is a software application. A standard for secure blockchain applications. A security vulnerability exists in OpenZeppelin Contracts versions prior to 5.0.2 and prior to 4.9.6, which stems from the fact that the last iteration of the Base64.encode function can read portions of memory...

Out-of-bounds Read

@openzeppelin/contracts, @openzeppelin/contracts-upgradeable are vulnerable to Out-of-bounds Read. The vulnerability is due to Base64.encode function which encodes a byte input by iterating over it in chunks of 3 byte and reading the parts of the memory beyond the input buffer when the input is n...

Signatures can be replayed to cast with castVoteWithReasonAndParamsBySig() more votes than the user intended in GovernorOLAS

Lines of code Vulnerability details Impact In the "GovernorOLAS.sol" contract, as the comment line supports the OpenZeppelin functions are used as is. However, the inherited OpenZeppelin 4.8.3 library exposes a signature replay vulnerability due to the lack of use of nonce in the...

GovernorOLAS is susceptible to DOS via proposal frontrunning

Lines of code Vulnerability details Impact The GovernorOLAS contract inherits from OpenZeppelin's GovernorCompatibilityBravo v4.8.3, which has a known vulnerability in the proposal creation process that can be exploited to halt proposals sent to the governor. The root cause of this vulnerability ...

Signature Malleability in CultureIndex::_verifyVoteSignature function

Lines of code Vulnerability details Impact The elliptic curve used in Ethereum for signatures is symmetrical, hence for every v,r,s there exists another v,r,s that returns the same valid result. Therefore two valid signatures exist which allows attackers to compute a valid signature without knowi...

No access control on critical functions

Lines of code Vulnerability details The contract lacks proper access control on critical functions, allowing unauthorized parties to execute them. Recommendation: Use OpenZeppelin Ownable control for minting/burning, etc. Before: // No access control checks in critical functions function...
