CVE-2026-4970 Overview
A SQL injection vulnerability has been discovered in code-projects Social Networking Site version 1.0. This security flaw affects the delete_photos.php file within the Endpoint component. The vulnerability allows remote attackers to manipulate the ID argument to inject arbitrary SQL commands, potentially leading to unauthorized data access, modification, or deletion.
Critical Impact
Remote attackers can exploit this SQL injection vulnerability to compromise database integrity, extract sensitive user information, and potentially gain unauthorized access to the underlying system.
Affected Products
- code-projects Social Networking Site 1.0
- delete_photos.php Endpoint component

Technical Details for CVE-2026-4970
Vulnerability Analysis
This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection-style vulnerabilities. The flaw exists in the delete_photos.php endpoint where user-supplied input through the ID parameter is not properly sanitized before being incorporated into SQL queries.
The exploit has been publicly disclosed, meaning that potential attackers have access to information that could be used to target vulnerable installations. The attack can be executed remotely over the network, requiring only low-level authentication privileges to exploit.
Root Cause
The root cause of this vulnerability is improper input validation and lack of parameterized queries in the delete_photos.php file. The ID parameter is directly concatenated into SQL statements without proper sanitization or use of prepared statements, allowing attackers to inject malicious SQL code that gets executed by the database engine.
Attack Vector
The attack vector for CVE-2026-4970 is network-based, allowing remote exploitation. An authenticated attacker with low privileges can craft malicious requests to the delete_photos.php endpoint, manipulating the ID parameter to inject SQL commands. This could allow the attacker to bypass authentication, extract sensitive data from the database, modify or delete records, or potentially escalate privileges within the application.
The vulnerability mechanism involves crafting malicious input for the ID parameter that breaks out of the intended SQL query context. For detailed technical analysis and proof-of-concept information, refer to the GitHub SQL Injection Analysis.
Detection Methods for CVE-2026-4970
Indicators of Compromise
- Unusual database queries containing SQL injection patterns such as UNION SELECT, OR 1=1, or comment sequences (--, /**/)
- Unexpected access to the delete_photos.php endpoint with malformed ID parameter values
- Database error messages appearing in application logs indicating SQL syntax errors
- Unauthorized data access or modification patterns in database audit logs
Detection Strategies
- Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to delete_photos.php
- Monitor application logs for requests containing suspicious characters in the ID parameter (single quotes, double dashes, semicolons)
- Deploy database activity monitoring to detect anomalous query patterns or unauthorized data access
- Configure intrusion detection systems (IDS) with signatures for common SQL injection attack payloads
Monitoring Recommendations
- Enable detailed logging for all requests to the delete_photos.php endpoint
- Set up alerts for database errors originating from the affected component
- Monitor for unusual patterns of photo deletion or database access outside normal usage hours
- Implement real-time monitoring of database query execution for injection patterns
How to Mitigate CVE-2026-4970
Immediate Actions Required
- Restrict access to the delete_photos.php endpoint until a patch is available
- Implement input validation for the ID parameter to accept only numeric values
- Deploy WAF rules to block SQL injection attempts targeting the vulnerable endpoint
- Review application logs for evidence of exploitation attempts
Patch Information
No official vendor patch has been released at the time of this writing. Organizations using code-projects Social Networking Site 1.0 should monitor the Code Projects Resources page for security updates. Additional vulnerability information is available at VulDB #353857.
Workarounds
- Implement a Web Application Firewall (WAF) with SQL injection detection rules
- Modify the delete_photos.php file to use parameterized queries or prepared statements instead of direct string concatenation
- Add server-side input validation to ensure the ID parameter contains only numeric values
- Consider temporarily disabling the photo deletion functionality until a proper fix can be implemented
- Apply the principle of least privilege to database accounts used by the application
# Example: Input validation for numeric ID parameter (PHP)
# Replace direct use of $_GET['ID'] with validated input:
# $id = filter_input(INPUT_GET, 'ID', FILTER_VALIDATE_INT);
# if ($id === false || $id === null) { die('Invalid ID'); }
# Use prepared statements with the validated $id value
