{"id":"GHSA-p6x5-p4xf-cc4r","summary":"Remote Code Execution (RCE) via String Literal Injection into math-codegen","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.","aliases":["CVE-2026-41507"],"modified":"2026-05-12T17:16:37.269274Z","published":"2026-04-17T22:31:45Z","database_specific":{"cwe_ids":["CWE-94"],"severity":"CRITICAL","github_reviewed":true,"github_reviewed_at":"2026-04-17T22:31:45Z","nvd_published_at":"2026-05-08T14:16:34Z"},"references":[{"type":"WEB","url":"https://github.com/mauriciopoppe/math-codegen/security/advisories/GHSA-p6x5-p4xf-cc4r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-41507"},{"type":"WEB","url":"https://github.com/mauriciopoppe/math-codegen/pull/11"},{"type":"WEB","url":"https://github.com/mauriciopoppe/math-codegen/commit/4bb52d3030683362b3559ee8dd91350555a05f6b"},{"type":"WEB","url":"https://github.com/hits3134"},{"type":"PACKAGE","url":"https://github.com/mauriciopoppe/math-codegen"}],"affected":[{"package":{"name":"math-codegen","ecosystem":"npm","purl":"pkg:npm/math-codegen"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.4.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/04/GHSA-p6x5-p4xf-cc4r/GHSA-p6x5-p4xf-cc4r.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
