CVE-2026-41507

math-codegen generates code from mathematical expressions.

Published May 8, 2026 · updated Jun 17, 2026 · mauriciopoppe math-codegen

math-codegen generates code from mathematical expressions. Prior to version 0.4.3, string literal content passed to cg.parse() is injected verbatim into a new Function() body without sanitization. This allows an attacker to execute arbitrary system commands when user-controlled input reaches the parser. Any application exposing a math evaluation endpoint where user input flows into cg.parse() is vulnerable to full RCE. This issue has been patched in version 0.4.3.
