> https://nvd.nist.gov/vuln/detail/CVE-2021-29425
> In Apache Commons IO before 2.7, When invoking the method
> FileNameUtils.normalize with an improper input string, like "//../foo", or
> "\\..\foo", the result would be the same value, thus possibly providing
> access to files in the parent directory, but not further above (thus
> "limited" path traversal), if the calling code would use the result to
> construct a path value.
> We don't use this API in the Hadoop code, but it's still good to update
> anyway (we're on 2.5, which is 4 years old)
