CVE-2026-5196 Overview
A SQL injection vulnerability has been identified in code-projects Student Membership System version 1.0. The vulnerability exists in the /delete_member.php file where the ID parameter is not properly sanitized before being used in SQL queries. This allows remote authenticated attackers to manipulate database queries by injecting malicious SQL code through the ID argument.
Critical Impact
Attackers can leverage this SQL injection vulnerability to extract, modify, or delete sensitive data from the application database, potentially compromising student membership records and related information.

Technical Details for CVE-2026-5196
Vulnerability Analysis
This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly known as injection. The /delete_member.php endpoint accepts an ID parameter that is passed directly to database operations without adequate input validation or parameterized queries. Since the exploit has been publicly disclosed, attackers with knowledge of this vulnerability can craft malicious requests to compromise the database backend.
The network-accessible nature of this vulnerability means that any authenticated user with access to the Student Membership System can potentially exploit this flaw remotely, making it a significant concern for organizations running this application.
Root Cause
The root cause of this vulnerability is improper input sanitization in the /delete_member.php file. The ID parameter is directly incorporated into SQL queries without being validated, sanitized, or used with parameterized statements. This classic SQL injection flaw allows attackers to break out of the intended query structure and execute arbitrary SQL commands.
Attack Vector
The attack is initiated remotely over the network by an authenticated user. An attacker sends a crafted HTTP request to the /delete_member.php endpoint with a malicious payload in the ID parameter. The unsanitized input is then executed as part of the SQL query, allowing the attacker to perform unauthorized database operations.
The vulnerability can be exploited by injecting SQL syntax into the ID parameter. For example, an attacker could modify the parameter to include SQL commands that bypass authentication checks, extract sensitive data using UNION-based attacks, or manipulate database records. Technical details about the exploitation methodology can be found in the GitHub CVE Issue Discussion and VulDB Vulnerability #354294.
Detection Methods for CVE-2026-5196
Indicators of Compromise
- Unusual or malformed requests to /delete_member.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
- Database error messages appearing in HTTP responses indicating SQL syntax errors
- Unexpected database query patterns in database logs showing injection attempts
- Anomalous deletion or modification of member records without corresponding legitimate user activity
Detection Strategies
- Implement web application firewall (WAF) rules to detect and block SQL injection patterns in request parameters
- Enable detailed logging for the /delete_member.php endpoint and monitor for suspicious parameter values
- Deploy intrusion detection systems (IDS) with SQL injection signature rules targeting the affected endpoint
- Review database audit logs for unusual query patterns or unauthorized data access
Monitoring Recommendations
- Monitor HTTP request logs for access to /delete_member.php with anomalous ID parameter values
- Set up alerts for database errors originating from the Student Membership System application
- Track changes to the members table for unauthorized modifications or deletions
- Implement real-time monitoring for SQL injection attack patterns across all application endpoints
How to Mitigate CVE-2026-5196
Immediate Actions Required
- Restrict access to the /delete_member.php endpoint to only trusted administrative users
- Implement input validation to ensure the ID parameter contains only numeric values
- Deploy a web application firewall (WAF) to filter SQL injection attempts
- Review application logs for evidence of exploitation attempts
Patch Information
No official vendor patch has been identified in the available CVE data. Organizations using code-projects Student Membership System 1.0 should contact the vendor via Code Projects for remediation guidance. Until a patch is available, apply the recommended workarounds below.
For additional technical details, refer to:
Workarounds
- Modify the application code to use parameterized queries or prepared statements for all database operations
- Implement strict input validation to allow only integer values for the ID parameter
- Deploy a reverse proxy or WAF with SQL injection filtering capabilities in front of the application
- Consider disabling the /delete_member.php functionality until a proper fix can be implemented
# Example: Restrict access to vulnerable endpoint via .htaccess
<Files "delete_member.php">
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
Allow from 192.168.1.0/24
</Files>
