CVE-2026-114115

Vyper 0.3.8 through 0.5.0b1 contains a compiler miscompilation vulnerability in parseIfExp that reads nested arrays with narrower inner bounds using the wider result type's memory layout. When a ternary selects the narrower array, inner arrays after the first are read at wrong offsets, causing...

CVE-2026-114115

Vyper versions 0.3.8 through 0.5.0b1 are affected by a compiler miscompilation vulnerability in parse_IfExp. The issue occurs when a ternary operator selects a nested array with narrower inner bounds, but the compiler uses the memory layout of the wider result type. This results in inner arrays a...

Vyperlang: Vyper buffer error vulnerability

In the version of VyperLang from 0.3.8 to 0.5.0b1, there is a buffer error vulnerability. This vulnerability stems from compiler errors in the parseIfExp function. The issue arises when using a wider result type for memory layout, which allows reading nested arrays with narrower inner boundaries...
