CVE-2026-49356

A flaw was found in @babel/core. This vulnerability allows an attacker, who controls the input source code and can read the output, to perform an arbitrary file read. By compiling maliciously crafted code containing a sourceMappingURL comment, the attacker can read any source map file from the system where Babel is running, leading to information disclosure.

Red Hat rates this issue as having Low impact for Red Hat AI products. @babel/core is bundled only in build-time or developer UI tooling (dashboard, model registry, MLflow) and the arbitrary file read requires local access and attacker-controlled source map processing that is not exposed in normal production use.
