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.
For Debian 9 stretch, this problem has been fixed in version 2.5-1+deb9u1.
We recommend that you upgrade your commons-io packages.
For the detailed security status of commons-io please refer to its security tracker page at: [link moved to references]
