Php SQL Injection (CVE-2026-26711)

Overview

A critical security vulnerability has been identified in the code-projects Simple Food Order System version 1.0. This flaw allows an attacker to perform SQL Injection attacks through a specific component of the application, potentially leading to a full compromise of the underlying database.

Vulnerability Details

The vulnerability exists in the /food/view-ticket.php file. In simple terms, the application does not properly validate or sanitize user-supplied input before using it to construct database queries. An attacker can exploit this by inserting malicious SQL code into input fields or URL parameters. The database then executes this malicious code as if it were a legitimate command.

This is a classic SQL Injection flaw, categorized as a CRITICAL severity issue with a CVSS score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating it is highly exploitable over a network with no privileges or user interaction required, and can lead to a complete loss of confidentiality, integrity, and system availability.

Potential Impact

If successfully exploited, this vulnerability can have severe consequences:

• Data Theft: An attacker can extract sensitive information from the database, including customer personal data, order details, and administrative credentials.
• Data Manipulation: Attackers can alter, delete, or corrupt data within the database, disrupting business operations.
• System Compromise: In some configurations, SQL Injection can be used as a stepping stone to execute commands on the underlying server, leading to a full system takeover.
• Compliance Violations: A breach could lead to violations of data protection regulations like GDPR or CCPA, resulting in significant legal fines and reputational damage.

Remediation and Mitigation

Immediate action is required for any deployment of Simple Food Order System v1.0.

Primary Remediation: The most effective solution is to apply a patch from the vendor. Contact the software provider (code-projects) to inquire about an official security update for CVE-2026-26711. If no patch is available, consider migrating to a supported and secure alternative system.

Immediate Mitigation Steps: If a patch cannot be applied immediately, take the following actions to reduce risk:

1. Input Validation and Parameterized Queries: A developer must rewrite the affected /food/view-ticket.php code to use prepared statements with parameterized queries. This is the standard defense, ensuring user input is treated as data, not executable code.
2. Web Application Firewall (WAF): Deploy or configure a WAF in front of the application to filter and block SQL Injection payloads. This is a temporary, network-level control and does not fix the root cause in the code.
3. Restrict Access: If possible, restrict network access to the application to only trusted users or IP ranges while a permanent fix is developed.
4. Review Logs: Monitor application and database logs for unusual query patterns or error messages that might indicate exploitation attempts.

General Advice: Always run software with the minimum necessary database privileges and ensure you are following a regular schedule for updating and reviewing the security of third-party applications in your environment.
