CVE-2026-5560

Vulnerability

Analysis

A SQL injection vulnerability has been identified in PHPGurukul Online Shopping Portal Project version 2.1. The flaw resides in the /payment-method.php file, where the paymethod parameter is processed without adequate sanitization or validation. User-supplied input is directly incorporated into SQL queries, enabling an attacker to manipulate the query structure by injecting malicious SQL fragments [2].

Exploitation

The vulnerability can be exploited remotely without authentication. An attacker can craft a POST request to /payment-method.php with a malicious paymethod parameter. Proof-of-concept payloads have been publicly disclosed, including time-based blind injection techniques using RLIKE SLEEP() to extract information or perform unauthorized actions [2]. The attack surface is accessible over the network, requiring no special privileges are not required, and user interaction is not needed.

Impact

Successful exploitation allows an attacker to gain unauthorized access to the underlying database. This can lead to sensitive data leakage (e.g., user credentials, order details), data tampering, or complete compromise of the database server. In severe cases, the attacker may gain control over the system and disrupt services, posing a significant threat to business operations [2].

Mitigation

As of the publication date, no official patch has been released by the vendor. The project's homepage references PHP Data Objects (PDO) for secure database interactions, but the vulnerable code does not implement parameterized queries [1]. Users are advised to apply input validation and use prepared statements with bound parameters to mitigate the risk until a vendor fix is available.
