PYSEC-2025-33

Vyper is a Pythonic Smart Contract Language for the EVM. When the Vyper Compiler uses the precompiles EcRecover 0x1 and Identity 0x4, the success flag of the call is not checked. As a consequence an attacker can provide a specific amount of gas to make these calls fail but let the overall executi...

Name of the Vulnerable Software and Affected Versions: Vyper versions 0.2.0 through 0.4.0 Description: The Vyper Compiler has a vulnerability when using the precompiles EcRecover 0x1 and Identity 0x4, where the success flag of the call is not checked. This allows an attacker to provide a specific...

Vyper 安全漏洞

Vyper is a Pythonic smart contract language for EVM open sourced by vyperlang. A security vulnerability exists in Vyper 0.4.0 and earlier versions, which stems from the compiler failing to check the success flag of a call when using pre-compiled EcRecover and Identity, which could lead to incorre...

Signature malleability can occur by using EVM's ecrecover

Lines of code Vulnerability details Impact EVM's ecrecover is susceptible to signature malleability which allows replay attacks, check this. Proof of Concept OffChainSignatureValidator in its function isValidSignature checks for signature validity by using vulnerable method of ecrecover. address...

CVE-2023-37902

Vyper is a Pythonic programming language that targets the Ethereum Virtual Machine EVM. Prior to version 0.3.10, the ecrecover precompile does not fill the output buffer if the signature does not verify. However, the ecrecover builtin will still return whatever is at memory location 0. This means...
