The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to deserialization of untrusted input via the 'path' parameter in versions up to, and including 0.9.74. This makes it possible for authenticated attackers with administrative privileges to call files using a PHAR wrapper that will deserialize and call arbitrary PHP Objects that can be used to perform a variety of malicious actions granted a POP chain is also present. It also requires that the attacker is successful in uploading a file with the serialized payload.

The Migration, Backup, Staging WordPress plugin before 0.9.70 does not sanitise and escape the sub_page parameter before outputting it back in the page, leading to a reflected Cross-Site Scripting
