CVE-2026-114117
Description
A flaw was found in Vyper. A remote attacker can cause smart contracts to execute with incorrect values due to an optimizer miscompilation. When compiling conditional branches containing certain bitwise operations under default optimization settings, the compiler incorrectly reduces the expression to a constant value. Consequently, affected contracts may perform storage writes and financial calculations using improper values without failing or reverting, potentially recording deposits incorrectly and locking funds.
