In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like โ€œ//โ€ฆ/fooโ€, or โ€œ\โ€ฆ\fooโ€, the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus โ€œlimitedโ€ path traversal), if the calling code would use the result to construct a path value.
