The Database Backup and check Tables Automated With Scheduler 2024 plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.32 via the database_backup_ajax_download() function. This makes it possible for authenticated attackers, with administrator-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information.
