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.
The CVSS severity warrants an early asset and exposure review.

Confirm exposure before applying a vendor-supported change.
Confirm that babel babel, plugin-transform-modules-systemjs and an affected version are present.
Combine exploitation signals with asset exposure and business criticality.
Follow the vendor advisory or supported update path and preserve rollback options.
Recheck the version, service health, access paths, and relevant logs.
