  "details": "### Impact\n\nString 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.\n    \n### Patches\n\nThe 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.\n    \n### Workarounds\n\nAvoid passing un-sanitized user input to the parser or manually escape string literals in the input.",
