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.","state":0,"publishedAt":"2026-04-17T22:31:45+00:00","modifiedAt":"2026-05-12T17:16:37.269274+00:00","affected":[{"ecosystem":"npm","name":"math-codegen","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"0.4.3"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"CRITICAL"}],"references":["https://github.com/mauriciopoppe/math-codegen/security/advisories/GHSA-p6x5-p4xf-cc4r","https://nvd.nist.gov/vuln/detail/CVE-2026-41507","https://github.com/mauriciopoppe/math-codegen/pull/11","https://github.com/mauriciopoppe/math-codegen/commit/4bb52d3030683362b3559ee8dd91350555a05f6b","https://github.com/hits3134","https://github.com/mauriciopoppe/math-codegen"],"sourceUrl":"https://github.com/advisories/GHSA-p6x5-p4xf-cc4r","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-p6x5-p4xf-cc4r","identifiers":["GHSA-p6x5-p4xf-cc4r","CVE-2026-41507"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
