CVE-2026-41507
Remote Code Execution (RCE) via String Literal Injection into math-codegen
CVSS Score
9.8
EPSS Score
0.0%
EPSS Percentile
0th
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.
