Summary
The School Management – Education & Learning ERP plugin for WordPress up to version 5.4 is vulnerable to SQL Injection via the 'order[0][dir]' parameter. Authenticated attackers with custom-level access and above can append SQL queries to existing ones, extracting sensitive database information. The vulnerability affects multiple AJAX handlers, and missing nonce verification enables CSRF-chained attacks.
Risk Assessment
Risk of database data leakage, including student, staff, and payment data, potentially leading to severe security and compliance breaches.
Recommendation
Update the School Management plugin to the latest version. Restrict access to administrative functions and implement additional protections like a web application firewall.

Original NVD description (English source)
The The School Management – Education & Learning ERP plugin for WordPress is vulnerable to generic SQL Injection via 'order[0][dir]' Parameter in all versions up to, and including, 5.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This vulnerability is replicated across seven or more AJAX handlers including wlsm-fetch-staff-classes, wlsm-fetch-notices, wlsm-fetch-subjects, wlsm-fetch-inquiries, wlsm-fetch-staff-employee, and wlsm-fetch-payments, and the missing nonce verification on several of these handlers also enables CSRF-chained exploitation.
