CVE-2017-14451

An exploitable out-of-bounds read vulnerability exists in libevm Ethereum Virtual Machine of CPP-Ethereum. A specially crafted smart contract code can cause an out-of-bounds read which can subsequently trigger an out-of-bounds write resulting in remote code execution. An attacker can create/send...

CVE-2025-46834 Alchemy's Modular Account can use executeUserOp to bypass allowlist prevalidation hook

Alchemy's Modular Account is a smart contract account that is compatible with ERC-4337 and ERC-6900. In versions on the 2.x branch prior to commit 5e6f540d249afcaeaf76ab95517d0359fde883b0, owners of Modular Accounts can grant session keys scoped external keys to external parties and would use the...

CVE-2025-27104

vyper is a Pythonic Smart Contract Language for the EVM. Multiple evaluation of a single expression is possible in the iterator target of a for loop. While the iterator expression cannot produce multiple writes, it can consume side effects produced in the loop body e.g. read a storage variable...

CVE-2025-27105

A flaw was found in Vyper, a Pythonic Smart Contract Language for the EVM. This vulnerability allows out-of-bounds writes via improper bounds checking when modifying a DynArray using an augmented assignment AugAssign. Mitigation Mitigation for this issue is either not available or the currently...

CVE-2025-26622

A flaw was found in Vyper’s sqrt builtin function. This vulnerability allows incorrect rounding of square root calculations via improper handling of oscillating final states in the Babylonian method. Mitigation Mitigation for this issue is either not available or the currently available options d...

CVE-2025-26622

vyper is a Pythonic Smart Contract Language for the EVM. Vyper sqrt builtin uses the babylonian method to calculate square roots of decimals. Unfortunately, improper handling of the oscillating final states may lead to sqrt incorrectly returning rounded up results. This issue is being addressed a...

CVE-2025-27105

vyper is a Pythonic Smart Contract Language for the EVM. Vyper handles AugAssign statements by first caching the target location to avoid double evaluation. However, in the case when target is an access to a DynArray and the rhs modifies the array, the cached target will evaluate first, and the...

CVE-2025-26622 sqrt doesn't define rounding behavior in Vyper

vyper is a Pythonic Smart Contract Language for the EVM. Vyper sqrt builtin uses the babylonian method to calculate square roots of decimals. Unfortunately, improper handling of the oscillating final states may lead to sqrt incorrectly returning rounded up results. This issue is being addressed a...

CVE-2025-27105 AugAssign evaluation order causing OOB write within the object in Vyper

vyper is a Pythonic Smart Contract Language for the EVM. Vyper handles AugAssign statements by first caching the target location to avoid double evaluation. However, in the case when target is an access to a DynArray and the rhs modifies the array, the cached target will evaluate first, and the...

CVE-2022-24787

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine. In version 0.3.1 and prior, bytestrings can have dirty bytes in them, resulting in the word-for-word comparisons giving incorrect results. Even without dirty nonzero bytes, two bytestrings can compare to equal if one en...

CVE-2022-46173

Elrond-GO is a go implementation for the Elrond Network protocol. Versions prior to 1.3.50 are subject to a processing issue where nodes are affected when trying to process a cross-shard relayed transaction with a smart contract deploy transaction data. The problem was a bad correlation between t...

CVE-2022-31172

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 allows some cases to...
