CVE-2026-37596 Overview
SourceCodester Online Employees Work From Home Attendance System v1.0 contains a SQL Injection vulnerability in the file /wfh_attendance/admin/manage_department.php. This web application vulnerability allows attackers to manipulate database queries through improperly sanitized user input, potentially leading to unauthorized data access.
Critical Impact
Authenticated attackers with administrative privileges can exploit this SQL Injection flaw to extract sensitive information from the database, compromising data confidentiality.

Technical Details for CVE-2026-37596
Vulnerability Analysis
This SQL Injection vulnerability (CWE-89) exists in the manage_department.php file of the administrative panel. The application fails to properly sanitize or parameterize user-supplied input before incorporating it into SQL queries. While the attack requires network access and high privileges (administrative authentication), successful exploitation allows attackers to read confidential database information.
The vulnerability requires an authenticated administrator to exploit, which limits the attack surface. However, in scenarios involving compromised admin credentials or insider threats, this flaw could be leveraged to extract sensitive employee attendance data, personal information, or other confidential records stored in the database.
Root Cause
The root cause of this vulnerability is improper input validation and the use of unsanitized user input directly within SQL query construction. The manage_department.php script fails to implement parameterized queries or prepared statements, allowing specially crafted input to modify the intended SQL query logic.
Attack Vector
The attack is executed over the network against the administrative interface. An attacker with valid administrative credentials can inject malicious SQL syntax through vulnerable parameters in the department management functionality. The injected payload manipulates the backend database query to extract data beyond what the application normally permits access to.
The vulnerability specifically affects the department management function, where user-controlled input is passed directly to database queries without proper escaping or parameterization. For detailed technical analysis and proof of concept, refer to the GitHub CVE Report.
Detection Methods for CVE-2026-37596
Indicators of Compromise
- Unusual SQL error messages in web server logs from the /wfh_attendance/admin/manage_department.php endpoint
- Suspicious parameter values containing SQL keywords (UNION, SELECT, OR, AND) in HTTP request logs
- Anomalous database query patterns or unexpected data access from the attendance system
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to the affected endpoint
- Monitor HTTP access logs for requests to manage_department.php containing suspicious characters or SQL syntax
- Configure database query logging to identify unusual or malformed queries originating from the application
Monitoring Recommendations
- Enable detailed logging for the administrative panel access, particularly the department management functionality
- Set up alerts for multiple failed database queries or SQL syntax errors from the same source
- Monitor for unauthorized data exports or bulk data access patterns from the attendance database
How to Mitigate CVE-2026-37596
Immediate Actions Required
- Restrict access to the administrative panel to trusted IP addresses only
- Review administrative user accounts and enforce strong authentication mechanisms
- Consider taking the affected application offline until a patched version is available
- Implement additional input validation at the web server or WAF level
Patch Information
No official vendor patch has been identified for this vulnerability. SourceCodester applications distributed through SourceCodester.com are community projects, and users should check the original source for any updates. As an alternative, organizations should consider implementing code-level fixes by modifying the manage_department.php file to use parameterized queries or prepared statements.
For additional technical details, see the GitHub CVE Report.
Workarounds
- Replace dynamic SQL queries with prepared statements using PDO or MySQLi with parameterized queries
- Implement strict input validation to allow only expected characters in department-related parameters
- Deploy a Web Application Firewall (WAF) with SQL injection protection rules
- Limit database user permissions for the application to only required operations (principle of least privilege)
# Example: Restrict access to admin panel via .htaccess
<Files "manage_department.php">
Order Deny,Allow
Deny from all
Allow from 192.168.1.0/24
</Files>
