CVE-2026-3759: Online Art Gallery Shop SQLi Vulnerability

CVE-2026-3759 Overview

A SQL injection vulnerability has been identified in Projectworlds Online Art Gallery Shop version 1.0. This security flaw exists within the /admin/adminHome.php file, where improper handling of the reach_nm parameter allows attackers to inject malicious SQL commands. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to sensitive database information, data manipulation, or complete database compromise.

Critical Impact
This SQL injection vulnerability enables remote attackers to execute arbitrary SQL commands against the backend database, potentially leading to data exfiltration, unauthorized data modification, or complete system compromise.

Affected Products

Projectworlds Online Art Gallery Shop version 1.0

Technical Details for CVE-2026-3759

Vulnerability Analysis

The vulnerability resides in the administrative interface of the Online Art Gallery Shop application, specifically within the adminHome.php file. The reach_nm parameter is not properly sanitized before being incorporated into SQL queries, creating an injection point that attackers can leverage to manipulate database operations. Since the vulnerability is accessible through the network and requires no authentication or user interaction, it presents a significant risk to deployments of this application.

The publicly disclosed nature of this exploit increases the urgency for organizations using this software to take immediate protective measures, as threat actors may already be scanning for vulnerable instances.

Root Cause

The root cause of this vulnerability is inadequate input validation and sanitization of the reach_nm parameter in the /admin/adminHome.php file. The application directly incorporates user-supplied input into SQL queries without proper parameterization or escaping, violating secure coding practices for database interactions.

This falls under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly known as Injection. The lack of prepared statements or parameterized queries allows attackers to break out of the intended query structure and inject arbitrary SQL commands.

Attack Vector

The attack can be executed remotely over the network by sending a specially crafted HTTP request to the vulnerable endpoint. An attacker would target the /admin/adminHome.php file and inject malicious SQL syntax through the reach_nm parameter. The exploit has been publicly disclosed and documented, making it accessible to potential attackers.

A typical attack scenario involves:

Identifying a target system running Projectworlds Online Art Gallery Shop 1.0
Crafting a malicious request to /admin/adminHome.php with SQL injection payload in the reach_nm parameter
Exploiting the injection point to extract sensitive data, modify records, or escalate privileges within the database

For technical details on the exploitation method, refer to the GitHub Issue Discussion and the VulDB entry.

Detection Methods for CVE-2026-3759

Indicators of Compromise

Unusual or malformed HTTP requests to /admin/adminHome.php containing SQL syntax characters in the reach_nm parameter
Database error messages in application logs indicating SQL syntax errors or unexpected query behavior
Unauthorized database queries appearing in database audit logs, particularly SELECT statements targeting sensitive tables
Evidence of data exfiltration or unexpected database modifications

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /admin/adminHome.php
Monitor HTTP access logs for requests containing common SQL injection payloads such as single quotes, UNION SELECT statements, or comment sequences
Enable database query logging and alert on queries with anomalous patterns or unauthorized data access attempts
Deploy application-level logging to capture and analyze all parameter values submitted to vulnerable endpoints

Monitoring Recommendations

Configure real-time alerting for any requests to /admin/adminHome.php containing suspicious characters or SQL keywords
Establish baseline metrics for database query patterns and alert on deviations that may indicate injection attempts
Monitor for reconnaissance activities such as repeated requests with incrementally modified payloads
Implement network-level monitoring to detect potential data exfiltration following successful exploitation

How to Mitigate CVE-2026-3759

Immediate Actions Required

Restrict access to the /admin/adminHome.php endpoint by implementing IP whitelisting or additional authentication controls
Consider taking the affected application offline if it contains sensitive data and cannot be immediately patched
Implement WAF rules to block SQL injection attempts targeting the reach_nm parameter
Review database logs for any signs of prior exploitation and assess potential data exposure

Patch Information

At the time of this writing, no official vendor patch has been released for this vulnerability. Organizations should monitor Projectworlds for security updates and apply patches as soon as they become available. As an open-source project, users may need to implement their own fixes or seek community-contributed patches.

For additional information, refer to the VulDB advisory and related GitHub issue.

Workarounds

Implement input validation at the application level to sanitize the reach_nm parameter before database queries
Deploy a Web Application Firewall with SQL injection detection capabilities in front of the application
Restrict database user privileges to limit the impact of successful SQL injection attacks
Consider migrating to parameterized queries or prepared statements if modifying the source code is feasible
