NewCVE-2026-41507 (opens in a new tab)How to fix?
Upgrade math-codegen to version 0.4.3 or higher.
Overview
math-codegen is a Generates code from mathematical expressions
Affected versions of this package are vulnerable to Arbitrary Code Injection via the parse function. An attacker can execute arbitrary code by supplying crafted input that is injected directly into a dynamically created function without proper sanitization.
Workaround
This vulnerability can be mitigated by avoiding the use of un-sanitized user input in the parser or by manually escaping string literals in the input.
