CVE-2026-5639

Vulnerability

Overview

A SQL injection vulnerability has been discovered in PHPGurukul Online Shopping Portal Project version 2.1. The flaw resides in the /admin/update-image3.php file, specifically within the handling of the filename parameter. The root cause is the lack of proper sanitization or validation of user-supplied input before it is used in SQL queries, enabling an attacker to inject malicious SQL code [2].

Exploitation

The attack can be executed remotely without authentication, as the vulnerable endpoint is accessible to any network user. An attacker can manipulate the filename parameter in a POST request to inject SQL commands. Proof-of-concept payloads have been published, including time-based blind SQL injection techniques using MySQL RLIKE [2].

Impact

Successful exploitation allows an attacker to gain unauthorized access to the underlying database. This can lead to sensitive data leakage, data tampering, and potentially full control over the database server, which could disrupt business operations [2].

Mitigation

As of the publication date, no official patch has been released by the vendor. The vendor's website provides general guidance on using PDO for secure database interactions [1], but the vulnerable application does not implement such measures. Users are advised to apply input validation and parameterized queries to mitigate the risk until a fix is available.
