CVE-2026-3758 identifies a SQL injection vulnerability in projectworlds Online Art Gallery Shop version 1.0, specifically within the /admin/adminHome.php script. The vulnerability arises from insufficient input validation or sanitization of the 'Info' parameter, which is directly incorporated into SQL queries. This allows an unauthenticated remote attacker to inject arbitrary SQL commands, potentially manipulating the underlying database. The vulnerability has a CVSS 4.0 base score of 6.9, indicating medium severity, with attack vector as network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impacts on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The scope remains unchanged (S:U). The exploit is publicly available, although no active exploitation has been reported yet. This vulnerability could allow attackers to extract sensitive data, modify or delete records, or disrupt service availability. The affected product is a niche online art gallery e-commerce platform, which may be used by small to medium enterprises or art vendors. No official patches have been linked yet, increasing the urgency for mitigation. The vulnerability highlights the critical need for secure coding practices, especially in administrative interfaces that control backend operations.

The SQL injection vulnerability allows attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data disclosure, data modification, or deletion. This compromises confidentiality, integrity, and availability of the affected system's data. For organizations, this could mean exposure of customer information, financial records, or intellectual property related to art sales. Attackers could also disrupt business operations by corrupting or deleting critical data. Since the vulnerability requires no authentication and no user interaction, it can be exploited remotely and easily, increasing the risk of automated attacks or mass scanning. The availability of a public exploit further raises the threat level, as less skilled attackers can leverage it. Organizations relying on this software for online sales or inventory management may face reputational damage, regulatory penalties, and financial losses if exploited. The impact is especially significant for businesses in the art and e-commerce sectors that handle sensitive customer and transaction data.

1. Immediate mitigation should include implementing strict input validation and parameterized queries or prepared statements in the /admin/adminHome.php script to prevent SQL injection. 2. Deploy a Web Application Firewall (WAF) configured to detect and block SQL injection patterns targeting the 'Info' parameter. 3. Restrict access to the /admin directory by IP whitelisting or VPN to limit exposure of the vulnerable interface. 4. Monitor database logs and web server logs for unusual query patterns or repeated failed attempts indicative of injection attempts. 5. If patching is not yet available, consider isolating the affected system or disabling the vulnerable functionality temporarily. 6. Conduct a thorough security audit of the entire application to identify and remediate other potential injection points. 7. Educate developers on secure coding practices, emphasizing the use of parameterized queries and input sanitization. 8. Regularly update and patch the software once official fixes are released by the vendor. 9. Implement least privilege principles for database accounts used by the application to limit potential damage. 10. Backup critical data regularly to enable recovery in case of data corruption or deletion.
