| Doc Text: |
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.
