The WPvivid Backup & Migration plugin for WordPress is vulnerable to SQL Injection via the export_data parameter in versions up to, and including, 0.9.131. This is due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. The values are received in prepare_export_post(), passed through sanitize_text_field() and stripslashes(), JSON-decoded, and the attacker-controlled JSON object keys are collected as $posts_ids without integer casting. They are stored in the export task options and later joined with commas and interpolated directly into a WHERE ID IN (...) clause inside a $wpdb->get_results() call in export_post_to_xml() (unquoted, numeric context), with no $wpdb->prepare() or esc_sql(). This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
