CVE-2026-3759 identifies a SQL injection vulnerability in projectworlds Online Art Gallery Shop version 1.0, specifically within the /admin/adminHome.php file. The vulnerability arises from improper sanitization of the 'reach_nm' parameter, which an attacker can manipulate to inject arbitrary SQL queries. This injection flaw allows remote attackers to execute unauthorized SQL commands without requiring authentication or user interaction, making it a network-exploitable vulnerability. The CVSS 4.0 base score is 6.9, reflecting medium severity due to the potential for partial impact on confidentiality, integrity, and availability, but with limited scope and no privilege or user interaction requirements. The vulnerability could enable attackers to extract sensitive data, modify database contents, or disrupt application functionality. Although no known exploits are currently active in the wild, the public disclosure of the exploit code increases the risk of future attacks. The absence of vendor patches or mitigations in the provided information suggests that affected organizations must implement immediate defensive measures. This vulnerability highlights the critical need for secure coding practices, especially in web applications handling administrative functions and sensitive data.

The SQL injection vulnerability in projectworlds Online Art Gallery Shop 1.0 can have significant impacts on organizations using this software. Attackers exploiting this flaw can gain unauthorized access to the backend database, potentially exposing sensitive customer information, transaction records, and administrative data. Data integrity could be compromised by unauthorized modifications or deletions, leading to business disruption and loss of trust. Availability might also be affected if attackers execute destructive queries or cause application crashes. Given that the vulnerability requires no authentication and can be exploited remotely, the attack surface is broad, increasing the likelihood of exploitation once the exploit is widely known. Organizations may face regulatory compliance issues if customer data is exposed, alongside reputational damage and financial losses. The impact is particularly critical for e-commerce platforms where data confidentiality and integrity are paramount for business continuity and customer trust.

To mitigate CVE-2026-3759, organizations should immediately implement the following measures: 1) Apply vendor patches or updates if available; since none are listed, contact the vendor for remediation guidance. 2) Employ strict input validation and sanitization on the 'reach_nm' parameter and all user-supplied inputs to prevent injection of malicious SQL code. 3) Refactor database queries to use parameterized statements or prepared queries, eliminating direct concatenation of user input into SQL commands. 4) Restrict database user permissions to the minimum necessary, limiting the potential damage from successful injection. 5) Implement Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the vulnerable parameter. 6) Conduct regular security assessments and code reviews focusing on injection flaws. 7) Monitor logs and network traffic for suspicious activities indicative of exploitation attempts. 8) Educate developers on secure coding practices to prevent similar vulnerabilities in future releases. These steps collectively reduce the risk and potential impact of exploitation.
