CVE-2026-44728 Details
Description
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.
A vulnerability exists in Babel versions 7.12.0 prior to 7.29.4 and 8.0.0-alpha.0 through 8.0.0-alpha.12. When using Babel to compile code crafted by an attacker, it can generate output that executes arbitrary code. This issue arises in the '@babel/plugin-transform-modules-systemjs' plugin and in '@babel/preset-env' when the 'modules: "systemjs"' option is used, as it relies on the 'plugin-transform-modules-systemjs' plugin. The vulnerability is not a concern for users who only compile trusted code.
The vulnerability has been fixed in '@babel/plugin-transform-modules-systemjs' version 7.29.4. Users of '@babel/preset-env' can update to version 7.29.5, which includes the patched 'plugin-transform-modules-systemjs' dependency. If a direct update is not possible, '@babel/parser' can be pinned to version 7.11.5, although this may disable some new language features and could cause build pipeline failures. Alternatively, the 'modules: "systemjs"' option can be avoided by migrating to native ES Modules or other module formats.
