Babel is a compiler for writing next generation JavaScript. From 7.12.0 to before 7.29.4 and 8.0.0-alpha.13, using Babel to compile code that was specifically crafted by an attacker can cause Babel to generate output code that executes arbitrary code. This vulnerability is fixed in 7.29.4 and 8.0.0-alpha.13.

GHSA-fv7c-fp4j-7gwp@babel/plugin-transform-modules-systemjs generates arbitrary code when compiling malicious input2026-05-08ghsa · osvUS
### Impact Using Babel to compile code that was specifically crafted by an attacker can cause Babel to generate output code that executes arbitrary code. Known affected plugins are: - `@babel/plugin-transform-modules-systemjs` - `@babel/preset-env` when using the [`modules: "systemjs"` option](https://babel.dev/docs/babel-preset-env#modules), as it delegates to `@babel/plugin-transform-modules-systemjs` No other plugins under the `@babel` namespace are impacted. **Users that only compile trusted code are not impacted.** ### Patches The vulnerability has been fixed in `@babel/plugin-transform-modules-systemjs@7.29.4`. Babel also released `@babel/preset-env@7.29.5`, updating its `@babel/plugin-transform-modules-systemjs` dependency, to simplify forcing the update if you are using `@babel/preset-env` directly. ### Workarounds - Pin `@babel/parser` to v7.11.5. The downgrade will completely disable string module name parsing, but it would also disable other new language features and the build pipeline may fail as a result. Only do so if you are working on a legacy codebase and can not upgrade `@babel/plugin-transform-modules-systemjs` to v7.29.4. - Do not use the `modules: "systemjs"` option, migrate the codebase to native ES Modules or any other module formats. ### Credits Babel thanks Daniel Cervera for reporting the vulnerability.
