GHSA-p6x5-p4xf-cc4r Remote Code Execution (RCE) via String Literal Injection into math-codegen

• npm math-codegen: < 0.4.3 → fixed in 0.4.3

Impact 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. Patches The vulnerability is addressed by using `JSON.stringify()` on string literal values in `lib/node/ConstantNode.js` to ensure they are treated as data rather than code. Users should upgrade to version 0.4.3 or later. Workarounds Avoid passing un-sanitized user input to the parser or manually escape string literals in the input.
