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."}], "lastModified": "2026-05-12T14:26:48.890", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:mauriciopoppe:math-codegen:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "8965334E-695A-4505-BADF-4FDDD9C14CC4", "versionEndExcluding": "0.4.3"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
