Input validation vulnerability in Backup Migration 1.4.6

The Backup Migration plugin for WordPress has a security issue that allows attackers to inject a harmful code into the website. This can be done by taking advantage of a function called ‘recursive_unserialize_replace’ which does not properly check for malicious input. This vulnerability exists in all versions of the plugin up to version 1.4.6. Attackers can use this exploit to delete important files, access sensitive information, or even run their own code on the website. To trigger this issue, an administrator must first create a staging site.
