CVE-2026-114116

Description

A flaw was found in Vyper. An attacker contributing source code can manipulate constant values in compiled contracts by embedding non-standard line-break characters into comments, strings, or indentation. Because the compiler interprets these line breaks differently from the underlying language parser, source text positions shift during validation. This flaw allows an attacker to silently alter critical values, such as financial amounts or account addresses, without detection during visual code inspection.
