CVE-2026-26712: Simple Food Order System SQLi Flaw

CVE-2026-26712 Overview

CVE-2026-26712 is a SQL Injection vulnerability affecting the Simple Food Order System v1.0 developed by Carmelo (code-projects). The vulnerability exists in the /food/view-ticket-admin.php endpoint, allowing attackers to inject malicious SQL commands through user-supplied input. This classic web application security flaw enables unauthorized database access, data exfiltration, and potential system compromise.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability to extract sensitive data, modify database contents, and potentially gain full control of the underlying database server.

Affected Products

• Carmelo Simple Food Order System version 1.0
• code-projects Simple Food Order System v1

Technical Details for CVE-2026-26712

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs in the administrative ticket viewing functionality of the Simple Food Order System. The /food/view-ticket-admin.php script fails to properly sanitize user input before incorporating it into SQL queries. This allows attackers to manipulate database queries by injecting crafted SQL statements through vulnerable parameters.

The vulnerability is particularly dangerous because it requires no authentication and can be exploited remotely over the network. Successful exploitation grants attackers the ability to read, modify, or delete data within the database, potentially exposing sensitive customer information, order details, and administrative credentials.

Root Cause

The root cause of this vulnerability is improper input validation and the use of unsanitized user input in SQL query construction. The application directly concatenates user-supplied data into SQL statements without proper parameterization or escaping, creating a classic SQL Injection attack surface. This represents a failure to implement secure coding practices for database interaction.

Attack Vector

The attack vector is network-based, requiring no prior authentication or user interaction. An attacker can send specially crafted HTTP requests to the vulnerable /food/view-ticket-admin.php endpoint, injecting SQL code through vulnerable parameters. The injected SQL commands execute with the privileges of the database user configured for the application, potentially allowing full database compromise.

Common exploitation techniques for this type of SQL Injection include:

• Union-based injection to extract data from other tables
• Boolean-based blind injection to enumerate database contents
• Time-based blind injection when direct output is not visible
• Stacked queries to execute multiple SQL statements (if supported)

Attackers can leverage tools like SQLMap to automate the exploitation process and extract database contents. For technical details on this vulnerability, refer to the GitHub SQL Injection Report.

Detection Methods for CVE-2026-26712

Indicators of Compromise

• Unusual SQL error messages in web server logs containing syntax errors or database information disclosure
• HTTP requests to /food/view-ticket-admin.php containing SQL keywords such as UNION, SELECT, OR 1=1, or comment sequences (--, /*)
• Abnormal database query patterns or increased query execution times
• Evidence of data exfiltration or unauthorized database access in application logs

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL Injection patterns targeting the /food/view-ticket-admin.php endpoint
• Implement database activity monitoring to identify suspicious query patterns and unauthorized data access
• Enable detailed logging for the Simple Food Order System application and web server
• Configure intrusion detection systems (IDS) with signatures for SQL Injection attack patterns

Monitoring Recommendations

• Monitor web server access logs for requests to /food/view-ticket-admin.php with suspicious query string parameters
• Set up alerting for database errors and unusual query patterns in database server logs
• Track failed authentication attempts and anomalous administrative access patterns
• Implement real-time monitoring for data exfiltration indicators such as large result sets or sensitive table access

How to Mitigate CVE-2026-26712

Immediate Actions Required

• Restrict access to the /food/view-ticket-admin.php endpoint using IP-based access controls or authentication
• Deploy a Web Application Firewall with SQL Injection protection rules in front of the application
• Disable the Simple Food Order System application if it is not critical until a patch is available
• Review database user privileges and apply principle of least privilege to limit potential damage

Patch Information

No vendor patch is currently available for CVE-2026-26712. The vulnerability was documented in a GitHub security report. Organizations should monitor for updates from the code-projects community or consider implementing manual code fixes using parameterized queries.

Workarounds

• Implement input validation and parameterized queries (prepared statements) in the vulnerable /food/view-ticket-admin.php script
• Deploy a reverse proxy with ModSecurity or similar WAF capabilities configured with OWASP Core Rule Set
• Restrict network access to administrative endpoints to trusted IP addresses only
• Consider using database user accounts with read-only privileges where full access is not required
