CVE-2025-15655 Overview
CVE-2025-15655 is an SQL Injection vulnerability in the Mojoomla School Management plugin for WordPress. The flaw exists in versions up to and including 93.2.0 and stems from improper neutralization of special elements used in an SQL command [CWE-89]. Authenticated attackers with high privileges can inject malicious SQL into backend database queries over the network. Successful exploitation impacts confidentiality across a changed scope and can degrade availability. The vulnerability was published to the National Vulnerability Database (NVD) on 2026-06-03.
Critical Impact
Attackers can extract sensitive student, staff, and administrative records from the WordPress database, with cross-scope impact reaching data outside the plugin's own boundary.
Affected Products
- Mojoomla School Management plugin for WordPress
- All versions from initial release through 93.2.0
- WordPress sites running the School Management plugin in default configuration

Technical Details for CVE-2025-15655
Vulnerability Analysis
The vulnerability resides in database query construction inside the School Management plugin. User-supplied input reaches SQL statements without proper sanitization or parameterization. An attacker holding an authenticated account with elevated privileges can inject crafted payloads through plugin parameters. The injected SQL executes in the context of the WordPress database user, exposing data in tables managed by the plugin and other tables in the same schema. The changed scope indicates the impact extends beyond the vulnerable component itself, reaching the broader WordPress database environment.
Root Cause
The root cause is improper neutralization of special characters in SQL statements [CWE-89]. The plugin concatenates request parameters directly into SQL queries rather than using prepared statements with bound parameters. WordPress provides the $wpdb->prepare() API for safe query construction, but the affected code paths bypass this protection. Input filtering and escaping are either missing or insufficient to block SQL metacharacters.
Attack Vector
The attack vector is network-based and requires authentication with high privileges. An attacker submits HTTP requests to plugin endpoints containing SQL syntax in vulnerable parameters. No user interaction is required. The vulnerability mechanism and parameter details are documented in the Patchstack SQL Injection Vulnerability advisory.
Detection Methods for CVE-2025-15655
Indicators of Compromise
- Unexpected SQL syntax such as UNION SELECT, OR 1=1, SLEEP(, or comment sequences in HTTP request parameters to School Management plugin endpoints.
- WordPress database error messages in server logs originating from plugin pages.
- Unusual queries against wp_users, wp_usermeta, or plugin-specific tables initiated from plugin handlers.
- Outbound data transfers from the web server immediately after authenticated requests to plugin URLs.
Detection Strategies
- Deploy a Web Application Firewall (WAF) with rules tuned to block SQL injection payloads against /wp-admin/admin.php and plugin AJAX endpoints.
- Enable MySQL general query logging during incident response and search for parameterized values containing SQL metacharacters.
- Review WordPress audit logs for high-privileged accounts performing unusual plugin actions.
Monitoring Recommendations
- Alert on HTTP 500 responses from School Management plugin URLs, which often indicate SQL syntax errors during probing.
- Monitor for spikes in request volume to plugin endpoints from a single authenticated session.
- Forward WordPress and web server logs to a centralized SIEM for correlation with authentication events.
How to Mitigate CVE-2025-15655
Immediate Actions Required
- Identify all WordPress installations running the Mojoomla School Management plugin at version 93.2.0 or earlier.
- Restrict access to WordPress administrative interfaces using IP allowlisting or VPN until a patched version is applied.
- Rotate credentials for high-privileged WordPress accounts and review recent administrative activity.
- Audit the WordPress database for unauthorized modifications and exported data.
Patch Information
No fixed version is listed in the NVD entry at the time of publication. Consult the Patchstack SQL Injection Vulnerability advisory and the Mojoomla vendor page for the latest patched release. Apply the update in a staging environment before promoting to production.
Workarounds
- Deactivate the School Management plugin until a patched version is installed.
- Apply virtual patching through a WAF with signatures for SQL injection targeting WordPress plugins.
- Reduce the number of accounts with administrator or editor privileges to limit the attacker pool.
- Enforce multi-factor authentication on all WordPress accounts that meet the privilege threshold for exploitation.
# Configuration example: temporarily deactivate the plugin via WP-CLI
wp plugin deactivate school-management
wp plugin status school-management
