  • CVE-2024-32481MedApr 25, 2024
    risk 0.28cvss 5.3epss 0.01

    Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. Starting in version 0.3.8 and prior to version 0.4.0b1, when looping over a `range` of the form `range(start, start + N)`, if `start` is negative, the execution will always revert. This issue is caused…

  • CVE-2024-32649MedApr 25, 2024
    risk 0.27cvss 5.3epss 0.00

    Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, using the `sqrt` builtin can result in double eval vulnerability when the argument has side-effects. It can be seen that the `build_IR` function of the `sqrt` builtin…

  • CVE-2024-32648MedApr 25, 2024
    risk 0.27cvss 5.3epss 0.00

    Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. Prior to version 0.3.0, default functions don't respect nonreentrancy keys and the lock isn't emitted. No vulnerable production contracts were found. Additionally, using a lock on a `default` function…

  • CVE-2024-32646MedApr 25, 2024
    risk 0.27cvss 5.3epss 0.00

    Vyper is a pythonic Smart Contract Language for the Ethereum virtual machine. In versions 0.3.10 and prior, using the `slice` builtin can result in a double eval vulnerability when the buffer argument is either `msg.data`, `self.code` or `.code` and either the `start`…

  • CVE-2023-42460MedSep 27, 2023
    risk 0.27cvss 5.3epss 0.01

    Vyper is a Pythonic Smart Contract Language for the EVM. The `_abi_decode()` function does not validate input when it is nested in an expression. Uses of `_abi_decode()` can be constructed which allow for bounds checking to be bypassed resulting in incorrect results. This issue…

  • CVE-2023-42441MedSep 18, 2023
    risk 0.27cvss 5.3epss 0.00

    Vyper is a Pythonic Smart Contract Language for the Ethereum Virtual Machine (EVM). Starting in version 0.2.9 and prior to version 0.3.10, locks of the type `@nonreentrant("")` or `@nonreentrant('')` do not produce reentrancy checks at runtime. This issue is fixed in version…

  • CVE-2023-37902MedJul 25, 2023
    risk 0.27cvss 5.3epss 0.00

    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…

  • CVE-2024-24560LowFeb 2, 2024
    risk 0.24cvss 3.7epss 0.01

    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…

  • CVE-2024-24567MedJan 30, 2024
    risk 0.24cvss 4.8epss 0.00

    Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. Vyper compiler allows passing a value in builtin raw_call even if the call is a delegatecall or a staticcall. But in the context of delegatecall and staticcall the handling of value is not possible due…

  • CVE-2024-26149LowFeb 26, 2024
    risk 0.17cvss 3.7epss 0.01

    Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. If an excessively large value is specified as the starting index for an array in `_abi_decode`, it can cause the read position to overflow. This results in the decoding of values outside the intended…

  • CVE-2024-24564LowFeb 26, 2024
    risk 0.17cvss 3.7epss 0.01

    Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. When using the built-in `extract32(b, start)`, if the `start` index provided has for side effect to update `b`, the byte array to extract `32` bytes from, it could be that some dirty memory is read and…

  • CVE-2024-24559LowFeb 5, 2024
    risk 0.17cvss 3.7epss 0.00

    Vyper is a Pythonic Smart Contract Language for the EVM. There is an error in the stack management when compiling the `IR` for `sha3_64`. Concretely, the `height` variable is miscalculated. The vulnerability can't be triggered without writing the `IR` by hand (that is, it cannot…

  • CVE-2023-41052LowSep 4, 2023
    risk 0.17cvss 3.7epss 0.00

    Vyper is a Pythonic Smart Contract Language. In affected versions the order of evaluation of the arguments of the builtin functions `uint256_addmod`, `uint256_mulmod`, `ecadd` and `ecmul` does not follow source order. This behaviour is problematic when the evaluation of one of…

  • CVE-2023-40015LowSep 4, 2023
    risk 0.17cvss 3.7epss 0.00

    Vyper is a Pythonic Smart Contract Language. For the following (probably non-exhaustive) list of expressions, the compiler evaluates the arguments from right to left instead of left to right. `unsafe_add, unsafe_sub, unsafe_mul, unsafe_div, pow_mod256, |, &, ^ (bitwise…

  • CVE-2023-32675LowMay 19, 2023
    risk 0.17cvss 3.7epss 0.01

    Vyper is a pythonic Smart Contract Language for the ethereum virtual machine. In contracts with more than one regular nonpayable function, it is possible to send funds to the default function, even if the default function is marked `nonpayable`. This applies to contracts…

  • CVE-2025-47774LowMay 15, 2025
    risk 0.12cvss epss 0.00

    Vyper is the Pythonic Programming Language for the Ethereum Virtual Machine. In versions up to and including 0.4.2rc1, the `slice()` builtin can elide side effects when the output length is 0, and the source bytestring is a builtin (`msg.data` or `.code`). The reason is…

  • CVE-2025-47285LowMay 15, 2025
    risk 0.12cvss epss 0.00

    Vyper is the Pythonic Programming Language for the Ethereum Virtual Machine. In versions up to and including 0.4.2rc1, `concat()` may skip evaluation of side effects when the length of an argument is zero. This is due to a fastpath in the implementation which skips evaluation of…

  • CVE-2022-24787HigApr 4, 2022
    risk 0.00cvss 7.5epss 0.01

    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…

  • CVE-2021-41121HigOct 6, 2021
    risk 0.00cvss 7.5epss 0.01

    Vyper is a Pythonic Smart Contract Language for the EVM. In affected versions when performing a function call inside a literal struct, there is a memory corruption issue that occurs because of an incorrect pointer to the the top of the stack. This issue has been resolved in…

  • CVE-2021-41122MedOct 5, 2021
    risk 0.00cvss 4.3epss 0.01

    Vyper is a Pythonic Smart Contract Language for the EVM. In affected versions external functions did not properly validate the bounds of decimal arguments. The can lead to logic errors. This issue has been resolved in version 0.3.0.
