CVE-2026-26710: Simple Food Order System SQLi Vulnerability

CVE-2026-26710 Overview

CVE-2026-26710 is a SQL Injection vulnerability identified in code-projects Simple Food Order System v1.0. The vulnerability exists in the /food/routers/edit-orders.php endpoint, allowing attackers to manipulate SQL queries through unsanitized user input. This type of vulnerability can lead to unauthorized database access, data theft, and potential system compromise.

Critical Impact

Unauthenticated attackers can exploit this SQL Injection vulnerability remotely to extract sensitive data, modify database contents, or potentially gain complete control over the backend database server.

Affected Products

• Carmelo Simple Food Order System v1.0
• code-projects Simple Food Order System v1

Technical Details for CVE-2026-26710

Vulnerability Analysis

This SQL Injection vulnerability (CWE-89) occurs in the edit-orders.php file within the /food/routers/ directory of the Simple Food Order System application. The vulnerability allows remote attackers to inject arbitrary SQL commands through user-controllable input parameters without requiring any authentication or user interaction.

SQL Injection vulnerabilities occur when user-supplied data is incorporated into SQL queries without proper sanitization or parameterization. In this case, the edit-orders.php endpoint fails to properly validate and escape input before constructing database queries, allowing malicious SQL code to be executed directly against the backend database.

Root Cause

The root cause of this vulnerability is improper input validation (CWE-89: Improper Neutralization of Special Elements used in an SQL Command). The application fails to implement prepared statements or parameterized queries when handling user input in the order editing functionality. Instead, user-supplied values are directly concatenated into SQL query strings, creating a classic SQL Injection attack surface.

Attack Vector

The attack vector is network-based, meaning attackers can exploit this vulnerability remotely over HTTP/HTTPS without requiring any authentication credentials. The vulnerable endpoint /food/routers/edit-orders.php can be targeted through crafted HTTP requests containing malicious SQL payloads in order-related parameters.

Exploitation requires no privileges and no user interaction, making this vulnerability particularly dangerous for internet-facing deployments. An attacker could manipulate order data, extract customer information, access administrative credentials stored in the database, or potentially escalate their access through database-level attacks.

Technical details about the specific vulnerable parameters and exploitation methodology can be found in the GitHub SQL Injection Report.

Detection Methods for CVE-2026-26710

Indicators of Compromise

• Unusual database queries in web server logs containing SQL syntax characters such as single quotes ('), double dashes (--), semicolons (;), or UNION keywords
• Abnormal access patterns to /food/routers/edit-orders.php with suspicious URL parameters
• Database errors or exceptions appearing in application logs indicating malformed SQL statements
• Unexpected data modifications in order-related database tables

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block common SQL Injection patterns targeting the edit-orders.php endpoint
• Implement database activity monitoring to detect anomalous query patterns or unauthorized data access
• Configure application logging to capture all requests to the vulnerable endpoint with full parameter details
• Enable SQL query logging at the database level to identify injection attempts

Monitoring Recommendations

• Monitor web server access logs for requests to /food/routers/edit-orders.php containing SQL metacharacters
• Set up alerts for database errors that indicate SQL syntax violations from the web application
• Review failed and successful authentication attempts in the database for anomalous patterns
• Track data extraction volumes from order-related tables to detect potential data exfiltration

How to Mitigate CVE-2026-26710

Immediate Actions Required

• Restrict network access to the vulnerable /food/routers/edit-orders.php endpoint immediately
• Deploy Web Application Firewall rules to block SQL Injection attack patterns
• Consider taking the Simple Food Order System offline until proper remediation can be implemented
• Conduct a database audit to check for signs of compromise or unauthorized data access

Patch Information

As of the last NVD update on 2026-03-03, no official vendor patch has been released for this vulnerability. Organizations using the Carmelo Simple Food Order System v1.0 should monitor for updates from the vendor. In the absence of an official patch, implementing the workarounds below is strongly recommended. Refer to the GitHub SQL Injection Report for additional technical details.

Workarounds

• Implement prepared statements with parameterized queries in the edit-orders.php file to prevent SQL injection
• Add strict input validation to sanitize all user-supplied data before database operations
• Deploy a reverse proxy with WAF capabilities to filter malicious SQL injection attempts
• Restrict database user privileges to minimum required permissions (principle of least privilege)
• Consider network segmentation to limit direct access to the application from untrusted networks

# Example: Restrict access to vulnerable endpoint using .htaccess
# Place in /food/routers/ directory

<Files "edit-orders.php">
    # Allow only trusted internal IP ranges
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
