CVE-2026-5606

Vulnerability

Description

The vulnerability resides in the /order-details.php file of PHPGurukul Online Shopping Portal Project version 2.1. The application fails to properly sanitize or validate the orderid POST parameter before incorporating it into SQL queries. This direct use of user-controlled input in database statements constitutes a classic SQL injection flaw [2].

Exploitation

Prerequisites

Attackers can exploit this vulnerability remotely without authentication by sending a crafted POST request to /order-details.php. The orderid parameter accepts malicious payloads, such as boolean-based blind injection strings (e.g., orderid=3' AND 7890=7890 AND 'zWdX'='zWdX). No special privileges or network position is required beyond standard HTTP access [2].

Impact

Successful exploitation allows an attacker to execute arbitrary SQL commands on the backend database. This can lead to unauthorized access to sensitive data (including customer information), data manipulation or deletion, and in some scenarios, full system compromise. The integrity and availability of the shopping portal are threatened [2].

Mitigation

As of the publication date, no official patch has been released by PHPGurukul. However, the PHP Data Objects (PDO) extension, discussed in the vendor's blog [1], provides prepared statements and parameterized queries which, if implemented, would eliminate this SQL injection risk by separating SQL logic from data. Administrators should apply input validation and use secure database access methods immediately.
