Description

The All-in-One Video Gallery plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the resolve_import_directory() function in versions 4.5.4 to 4.5.7. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
