CVE-2025-54070 OpenZeppelin Contracts's Bytes's lastIndexOf function with position argument performs out-of-bound memory access on empty buffers

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...

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...

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...
