Improper Synchronisation

https://github.com/evmos/evmos/ is vulnerable to Improper Synchronisation. The vulnerability is due to a lack of synchronization between two states during transaction execution, allowing for arbitrary token minting. This exploit occurs because the stateDB.Commit method updates the Cosmos SDK...

Improper Access Control

github.com/evmos/evmos is vulnerable to Improper Access Control. The vulnerability is due to Evmos allowing the creation of a vesting account at a designated address for smart contracts on the EVM, enabling attackers to front-run the creation of a contract and block legitimate contract deployment...

Evmos vulnerable to unauthorized account creation with vesting module

Impact What kind of vulnerability is it? Who is impacted? Using the vesting module, a malicious attacker can create a new vesting account at a given address, before a contract is created on that address. Addresses of smart contracts deployed to the EVM are deterministic. Therefore, it would be...

PYSEC-2024-148

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine. When calls to external contracts are made, we write the input buffer starting at byte 28, and allocate the return buffer to start at byte 0 overlapping with the input buffer. When checking RETURNDATASIZE for dynamic...

CVE-2024-24560 Vyper external calls can overflow return data to return input buffer

Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine. When calls to external contracts are made, we write the input buffer starting at byte 28, and allocate the return buffer to start at byte 0 overlapping with the input buffer. When checking RETURNDATASIZE for dynamic...

Vyper Code Issue Vulnerability

Vyper is the Pythonic smart contract language for EVM. A code issue vulnerability exists in Vyper version 0.3.10 and prior versions that stems from not disabling static and delegate calls...

Vyper Buffer Error Vulnerability

Vyper is a Pythonic smart contract language for EVM open sourced by vyperlang. A buffer error vulnerability exists in Vyper 0.3.10 and earlier versions, which stems from allowing concat to write to memory buffer boundaries built-in, thereby overwriting existing valid data...
