CVE-2026-2212 is a SQL injection vulnerability identified in the code-projects Online Music Site version 1.0, specifically within the /Administrator/PHP/AdminEditCategory.php script. The vulnerability stems from insufficient input validation and sanitization of the 'ID' parameter, which is manipulated by attackers to inject malicious SQL queries. This flaw allows unauthenticated remote attackers to execute arbitrary SQL commands on the backend database, potentially leading to unauthorized data access, modification, or deletion. The vulnerability does not require any privileges or user interaction, making it highly accessible for exploitation. The CVSS 4.0 base score is 6.9 (medium severity), reflecting the network attack vector, low complexity, and no required authentication, but limited impact on confidentiality, integrity, and availability. Although no active exploitation has been reported, a public exploit is available, increasing the likelihood of future attacks. The vulnerability affects only version 1.0 of the product, which is used primarily in online music platforms for administrative category management. The lack of patches or official fixes necessitates immediate mitigation through secure coding practices and access control. This vulnerability highlights the critical need for input validation and parameterized queries in web applications handling administrative functions.

For European organizations using code-projects Online Music Site 1.0, this vulnerability poses a significant risk to the confidentiality, integrity, and availability of their backend databases. Exploitation could lead to unauthorized disclosure of sensitive data, such as user information or proprietary content, data tampering that could disrupt service operations, or deletion of critical records impacting service availability. Given the administrative nature of the affected script, attackers might gain control over category management, potentially affecting content organization and user experience. The remote and unauthenticated nature of the exploit increases the attack surface, especially for organizations exposing the administrative interface to the internet. This could result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data breaches), and financial losses. The presence of a public exploit further elevates the risk of automated or targeted attacks against vulnerable installations in Europe.

1. Immediately restrict access to the /Administrator/PHP/AdminEditCategory.php endpoint using network-level controls such as IP whitelisting or VPN-only access to limit exposure. 2. Implement robust input validation and sanitization on the 'ID' parameter to ensure only expected numeric or alphanumeric values are accepted. 3. Refactor the code to use parameterized queries or prepared statements to prevent SQL injection attacks. 4. Conduct a comprehensive security audit of the entire application to identify and remediate similar injection flaws. 5. Monitor web server and database logs for suspicious activities targeting the vulnerable endpoint. 6. If possible, upgrade to a patched or newer version of the software once available. 7. Educate administrators and developers on secure coding practices and the risks of SQL injection. 8. Employ Web Application Firewalls (WAFs) with rules to detect and block SQL injection attempts targeting the affected parameter. 9. Regularly back up databases and test restoration procedures to minimize impact in case of data compromise.
