CVE-2026-26695: Student Alumni System SQLi Vulnerability

CVE-2026-26695 Overview

CVE-2026-26695 is a SQL Injection vulnerability affecting code-projects Simple Student Alumni System v1.0. The vulnerability exists in the /TracerStudy/recordstudent_edit.php endpoint, allowing unauthenticated attackers to execute arbitrary SQL queries against the underlying database. This type of vulnerability (CWE-89: Improper Neutralization of Special Elements used in an SQL Command) can lead to complete database compromise, including unauthorized data access, modification, and deletion.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability to extract sensitive student and alumni data, modify database records, or potentially gain further system access through database command execution.

Affected Products

• Carmelo Simple Student Alumni System version 1.0
• /TracerStudy/recordstudent_edit.php endpoint

Technical Details for CVE-2026-26695

Vulnerability Analysis

This SQL Injection vulnerability in Simple Student Alumni System v1.0 allows remote attackers to manipulate database queries through the /TracerStudy/recordstudent_edit.php endpoint. The application fails to properly sanitize user-supplied input before incorporating it into SQL queries, enabling attackers to inject malicious SQL statements. As this vulnerability requires no authentication or user interaction and is accessible over the network, it presents a significant risk to any deployment of this application.

Root Cause

The root cause of this vulnerability is improper input validation and lack of parameterized queries in the recordstudent_edit.php file. User-controlled input is directly concatenated into SQL query strings without proper sanitization or the use of prepared statements, allowing attackers to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The vulnerability is exploitable remotely over the network without requiring authentication. An attacker can craft malicious HTTP requests to the /TracerStudy/recordstudent_edit.php endpoint containing SQL injection payloads. These payloads can be used to:

• Extract sensitive data from the database (student records, alumni information, credentials)
• Modify or delete database records
• Bypass authentication mechanisms
• Potentially execute operating system commands if database privileges allow

Additional technical details are available in the GitHub Bug Report.

Detection Methods for CVE-2026-26695

Indicators of Compromise

• Unusual SQL error messages in web server logs from /TracerStudy/recordstudent_edit.php
• HTTP requests to recordstudent_edit.php containing SQL metacharacters such as single quotes, double dashes, or UNION statements
• Database query logs showing unexpected queries or time-based delays indicative of blind SQL injection
• Abnormal data access patterns or bulk data extraction from student/alumni tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect SQL injection patterns in requests to the affected endpoint
• Implement database activity monitoring to detect anomalous query patterns or unauthorized data access
• Enable detailed logging on the web application to capture suspicious input parameters
• Use intrusion detection systems (IDS) with SQL injection signature rules

Monitoring Recommendations

• Monitor access logs for the /TracerStudy/recordstudent_edit.php endpoint for unusual request patterns
• Set up alerts for SQL error messages appearing in application logs
• Implement rate limiting on the vulnerable endpoint to slow potential automated exploitation attempts
• Review database audit logs regularly for unauthorized access or data exfiltration attempts

How to Mitigate CVE-2026-26695

Immediate Actions Required

• Restrict access to the /TracerStudy/recordstudent_edit.php endpoint until a patch is applied
• Implement WAF rules to block known SQL injection patterns
• Consider taking the affected application offline if it contains sensitive data and cannot be adequately protected
• Review database permissions to ensure the application uses a least-privilege database account

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Organizations using Simple Student Alumni System v1.0 should monitor the vendor's communications for security updates. The vulnerability was reported via a GitHub Bug Report.

Workarounds

• Implement input validation and parameterized queries in the recordstudent_edit.php file to prevent SQL injection
• Use a Web Application Firewall (WAF) configured with SQL injection protection rules
• Restrict network access to the application to trusted IP addresses only
• Disable the TracerStudy functionality if not required for operations

# Example: Apache .htaccess to restrict access to vulnerable endpoint
<Files "recordstudent_edit.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
