CWE-359 Exposure of Private Personal Information to an Unauthorized Actor

CWE-36 Absolute Path Traversal

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize absolute path sequences such as "/abs/path" that can resolve to a location that is outside of that directory.
