CVE-2026-5017: SQL Injection in code-projects Simple Food Order System (Tickets)

CVE-2026-5017: SQL Injection in Simple Food Order System Ticket Handler

A SQL injection vulnerability tracked as CVE-2026-5017 has been disclosed in code-projects Simple Food Order System 1.0, a PHP-based open-source food ordering management application. The flaw resides in the /all-tickets.php endpoint's Status parameter handler and is remotely exploitable, making it a significant risk for any internet-accessible deployment of this software.

The vulnerability was assigned a CVSS v3.1 score of 7.3 (High) and classified under CWE-89 — Improper Neutralization of Special Elements used in SQL Commands.

Vulnerability Overview

Technical Details

Affected Component

The vulnerability exists in the ticket management module of the food order admin panel. The /all-tickets.php file accepts a Status GET or POST parameter and passes it directly into a SQL query without sanitization or parameterization, allowing an attacker to inject arbitrary SQL.

Exploitation Mechanism

An attacker with access to the ticket listing endpoint can manipulate the Status parameter to inject SQL:

/all-tickets.php?Status=1' OR '1'='1
/all-tickets.php?Status=1 UNION SELECT NULL,NULL,NULL,NULL--

Depending on the database configuration, successful exploitation could allow:

• Full database read access — extraction of all order, customer, and credential records
• Authentication bypass — if Status influences session or access logic
• Data exfiltration — customer PII, order history, and payment details
• Credential harvesting — extraction of hashed or plaintext admin passwords

Attack Flow

1. Attacker locates an internet-exposed Simple Food Order System instance

2. Attacker probes /all-tickets.php with malformed Status parameter

3. Injection payload executes against unsanitized SQL query

4. Backend database returns injected query results to the attacker

5. Attacker extracts customer data, credentials, and order records

6. Harvested credentials enable full admin panel compromise

Affected Software Context

code-projects distributes free PHP web application source code for academic and learning purposes. The Simple Food Order System 1.0 is intended as a learning tool for PHP developers. Despite this educational intent, these applications are regularly deployed in production settings without security hardening — particularly by small food service businesses, academic projects, or developers who download and deploy without reviewing security posture.

Multiple SQL injection CVEs have been disclosed across code-projects applications in recent months, indicating a systemic pattern of missing input validation across their PHP codebase.

Remediation

Immediate Steps

No official patch has been released. Deployments should apply the following mitigations immediately:

1. Restrict public access — Block /all-tickets.php from internet exposure using firewall rules or .htaccess restrictions
2. Deploy a WAF — Use ModSecurity, Cloudflare WAF, or equivalent with SQL injection detection enabled
3. Parameterize queries — Replace raw SQL string construction with prepared statements (PDO or MySQLi)
4. Rotate credentials — If the application has been internet-accessible, assume database credentials are compromised
5. Audit logs — Review server access logs for anomalous requests targeting the tickets endpoint

Code-Level Fix

The root cause is direct parameter interpolation into SQL queries. The fix requires prepared statements:

// Vulnerable pattern
$query = "SELECT * FROM tickets WHERE Status = '" . $_GET['Status'] . "'";
 
// Secure pattern (PDO prepared statement)
$stmt = $pdo->prepare("SELECT * FROM tickets WHERE Status = ?");
$stmt->execute([$_GET['Status']]);

Impact Assessment

Key Takeaways

1. CVE-2026-5017 is a CVSS 7.3 SQL injection in code-projects Simple Food Order System 1.0, affecting /all-tickets.php
2. The Status parameter is passed unsanitized into SQL queries, enabling direct database manipulation
3. A public exploit has been released, raising urgency for any production deployment
4. No official patch exists — access restriction and WAF deployment are the primary mitigations
5. This is part of a broader pattern of SQL injection vulnerabilities across code-projects PHP applications
