Session version 1.17.5 allows obtaining internal application files and public files from the user's device without the user's consent. This is possible because the application is vulnerable to Local File Read via chat attachments.
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.
