Vulnerability Title
Possible limited path traversal vulnerabily in Apache Commons IO
Source: CVE Program / CVE List V5
Vulnerability Description
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.
