Last modified
CVE-2026-114115 is a low-severity vulnerability rated 3.7/10 on the CVSS scale. Vyper 0.3.8 through 0.5.0b1 contains a compiler miscompilation vulnerability in parse_IfExp 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 contracts to silently store corrupted values or revert.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
