Uncode <= 2.9.1.6 - Unauthenticated Arbitrary File Read in uncode_admin_get_oembed

The Uncode theme for WordPress is vulnerable to arbitrary file read due to insufficient input validation in the 'uncode_admin_get_oembed' function in all versions up to, and including, 2.9.1.6. This makes it possible for unauthenticated attackers to read arbitrary files on the server.
