The MainWP Child Reports plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.2. This is due to missing or incorrect nonce validation on the networkoptionsaction() function. This makes it possible for unauthenticated attackers to update arbitrary options that can be leveraged for privilege escalation via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. This is only exploitable on multisite instances.

The MainWP Child plugin for WordPress is vulnerable to Sensitive Information Exposure in versions up to, and including, 4.4.1.1 due to insufficient controls on the storage of back-up files. This makes it possible for unauthenticated attackers to extract sensitive data including the entire installations database if a backup occurs and the deletion of the back-up files fail.
