All-in-One WP Migration and Backup < 7.108 - Multisite Subsite Admin+ Network-Wide PHP Code Execution via REST Import

Description

The plugin does not restrict its migration import functionality to network administrators on multisite installations, allowing an administrator of a single subsite to execute arbitrary PHP code across the entire network.

The affected user is not a network super administrator and is otherwise denied the ability to install plugins or themes, so this crosses the tenant separation boundary that multisite exists to enforce.
