The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect integrity, and availability. CVE summarizes:

The WPS Office (aka cn.wps.moffice_eng) application before 17.0.0 for Android fails to properly sanitize file names before processing them through external application interactions, leading to a form of path traversal.
