The Migration, Backup, Staging – WPvivid plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 0.9.107 via deserialization of untrusted input in the 'replace_row_data' and 'replace_serialize_data' functions.

If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code. An administrator must create a staging site to trigger the exploit.
