CVE-2020-37287
Vyper before 0.2.6 contains a call stack corruption vulnerability that causes incorrect function outputs when complex types with non-base members are passed as arguments. Contracts passing multi-dimensional arrays or structs to internal or external functions receive corrupted values because the...

CVE-2020-37288 Vyper 0.1.0b10 before 0.2.3 Invalid Jump Destination via Return in Nested Loops
Vyper from 0.1.0b10 before 0.2.3 generates incorrect code for a return statement inside a for loop in an internal function called two or more internal calls deep, producing an invalid jump destination stack underflow. Affected contracts revert such calls unnecessarily, which in limited...
CVE-2020-37287 Vyper before 0.2.6 Call Stack Corruption via Complex Type Function Arguments
Vyper before 0.2.6 contains a call stack corruption vulnerability that causes incorrect function outputs when complex types with non-base members are passed as arguments. Contracts passing multi-dimensional arrays or structs to internal or external functions receive corrupted values because the...

CVE-2020-37288
Vyper versions 0.1.0b10 before 0.2.3 are vulnerable to an invalid jump destination caused by a stack underflow . This occurs when a return statement is used inside a for loop within an internal function that is called two or more internal calls deep. The compiler generates incorrect code for thes...
CVE-2020-37287
Vyper versions prior to 0.2.6 are susceptible to a call stack corruption vulnerability. The root cause is an incorrect assumption by the compiler that each subtype size is 32, which occurs when complex types with non-base members are passed as function arguments. This flaw leads to corrupted func...

CVE-2020-37286 Vyper 0.1.0b4 before 0.3.0 Memory Corruption via Nested Internal Function Calls
Vyper from 0.1.0b4 before 0.3.0 contains a memory corruption vulnerability caused by an incorrect stack tip pointer when internal function calls appear inside tuples or nested calls. Contracts using such calls as tuple elements, call arguments, or builtin arguments like concat or ecrecover can...

CVE-2020-37286
Vyper versions 0.1.0b4 before 0.3.0 are vulnerable to a memory corruption issue caused by an incorrect stack tip pointer . This occurs when internal function calls are nested within tuples or other nested calls. Consequently, contracts using these calls as tuple elements, call arguments, or as ar...

Vyper 0.1.0b1 before 0.1.0b12, 0.1.0b14, and 0.4.1 through 0.5.0b1 mix character-based line offsets with Python's UTF-8 byte col offset values in vyper/ast/parse.py, so multi-byte characters shift the source slices used to reconstruct later numeric literals. An attacker contributing source with...

PT-2026-120242
Vyper 0.1.0b1 before 0.1.0b17 and 0.4.1 through 0.5.0b1 builds its source-line table with str.splitlines, which treats characters like form feed and U+2028 as line breaks the Python parser ignores, so numeric literals are classified and validated from shifted source text. An attacker contributing...

PT-2026-120244
Vyper 0.3.4 through 0.5.0b1 computes the remaining blueprint size in create from blueprint by uint256 subtraction without first checking that code offset is below the blueprint's code size, so a huge offset wraps to a small positive value. An attacker controlling code offset can make a factory...
PT-2026-120158
Vyper before 0.3.1 lacks a uint8 type, allowing interface return values declared as uint8, such as ERC20.decimals, to be stored in uint256 variables without bounds checking. Malicious contracts can return values greater than 255 to manipulate or bypass contract logic that relies on these values...

Vyper from 0.1.0b4 before 0.3.0 contains a memory corruption vulnerability caused by an incorrect stack tip pointer when internal function calls are performed inside arrays. Contracts placing internal calls in nested array elements, external call arguments, struct literals, or raw log topics can...
