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...

PT-2025-29948 · Openzeppelin · Openzeppelin Contracts

Name of the Vulnerable Software and Affected Versions: OpenZeppelin Contracts versions 5.2.0 through 5.3.9 Description: The lastIndexOfbytes,byte,uint256 function within the Bytes.sol library may access uninitialized memory under specific conditions. This occurs when the provided buffer length is...

OpenZeppelin Contracts 缓冲区错误漏洞

OpenZeppelin Contracts is a secure smart contract development library open-sourced by OpenZeppelin. A buffer error vulnerability exists in OpenZeppelin Contracts versions prior to 5.4.0, which stems from the lastIndexOf function potentially accessing uninitialized memory, potentially resulting in...

PromptChain: a Decentralized Web3 Architecture for Managing AI Prompts As Digital Assets

We present PromptChain, a decentralized Web3 architecture that establishes AI prompts as first-class digital assets with verifiable ownership, version control, and monetization capabilities. Current centralized platforms lack mechanisms for proper attribution, quality assurance, or fair...

Giving AI Agents Access to Cryptocurrency and Smart Contracts Creates New Vectors of AI Harm

There is growing interest in giving AI agents access to cryptocurrencies as well as to the smart contracts that transact them. But doing so, this position paper argues, could lead to formidable new vectors of AI harm. To support this argument, we first examine the unique properties of...

Wrapless: the Trustless Lending Protocol on Top of Bitcoin

This paper presents Wrapless -- a lending protocol that enables the collateralization of bitcoins without requiring a trusted wrapping mechanism. The protocol facilitates a "loan channel" on the Bitcoin blockchain, allowing bitcoins to be locked as collateral for loans issued on any blockchain th...

Static Analysis for Detecting Transaction Conflicts in Ethereum Smart Contracts

Ethereum smart contracts operate in a concurrent environment where multiple transactions can be submitted simultaneously. However, the Ethereum Virtual Machine EVM enforces sequential execution of transactions within each block to prevent conflicts arising from concurrent access to the same state...

Reliability Analysis of Smart Contract Execution Architectures: a Comparative Simulation Study

The industrial market continuously needs reliable solutions to secure autonomous systems. Especially as these systems become more complex and interconnected, reliable security solutions are becoming increasingly important. One promising solution to tackle this challenge is using smart contracts...

PhishingHook: Catching Phishing Ethereum Smart Contracts Leveraging EVM Opcodes

GHSA-G3QG-6746-3MG9 zkVM Underconstrained Vulnerability

Due to a missing constraint in the rv32im circuit, any 3-register RISC-V instruction including remu and divu in risc0-zkvm 2.0.0, 2.0.1, and 2.0.2 are vulnerable to an attack by a malicious prover. The main idea for the attack is to confuse the RISC-V virtual machine into treating the value of th...
