Path traversal vulnerability exists in Download Plugins and Themes from Dashboard versions prior to 1.8.6. If this vulnerability is exploited, a remote authenticated attacker with "switch_themes" privilege may obtain arbitrary files on the server.
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.
