Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Weblizar The School Management – Education & Learning Management allows SQL Injection.This issue affects The School Management – Education & Learning Management: from n/a through 4.1.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A SQL Injection vulnerability exists in the Weblizar The School Management WordPress plugin (versions through 4.1). The vulnerability allows unauthenticated attackers to inject malicious SQL commands through improper neutralization of special elements in SQL queries, potentially enabling unauthorized data access, modification, or deletion.

MitigationUpdate the Weblizar The School Management plugin to the latest patched version beyond 4.1. If no update is available, manually audit and remediate the vulnerable code by implementing parameterized queries (prepared statements) with proper input validation.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Weblizar School Management plugin is installed
    Check the WordPress plugins directory (wp-content/plugins/) for a folder named 'the-school-management' or similar, or query the wp_posts table for plugin-related entries. Alternatively, check the plugin's main PHP file header for version information.
    Affected if The plugin folder exists in the WordPress installation and the version header in the main plugin file shows a version lower than 4.2
  2. Confirm the plugin is active
    Query the WordPress options table (wp_options) where option_name = 'active_plugins', or check through WordPress admin dashboard plugins list.
    Affected if The plugin appears in the list of active plugins
  3. Identify the vulnerable SQL endpoint
    Review plugin source code for SQL query patterns that use unsanitized input, typically in files handling front-end submissions or ajax requests. Look for $wpdb->prepare() calls with direct $_POST, $_GET, or $_REQUEST variables that are not sanitized using functions like sanitize_text_field().
    Affected if The plugin contains PHP files with SQL queries that directly incorporate request parameters without proper escaping or prepared statements
  4. Test for SQL injection vulnerability (optional/authorized only)
    If authorized, send a crafted request to suspected vulnerable endpoints (often in ajax or frontend forms) with SQL meta-characters in parameters (e.g., single quotes) and observe for SQL errors or unexpected behavior.
    Affected if The application returns database errors or exhibits unexpected behavior when special SQL characters are submitted

The environment is affected if the Weblizar School Management plugin version is lower than 4.2 and the plugin is active on the WordPress site, exposing unauthenticated SQL injection entry points.
