There exists a command injection vulnerability in the WordPress plugin wp-database-backup for versions less than 5.2. For the backup functionality, the plugin generates a mysqldump command to execute. The user can choose specific tables to exclude from the backup by setting the wp_db_exclude_table parameter in a POST request to the wp-database-backup page. The names of the excluded tables are included in the mysqldump command unsanitized. Arbitrary commands injected through the wp_db_exclude_table parameter are executed each time the functionality for creating a new database backup are run. Authentication is required to successfully exploit this vulnerability.
