CVE-2026-2211 identifies a SQL injection vulnerability in the code-projects Online Music Site version 1.0, specifically within the /Administrator/PHP/AdminDeleteCategory.php script. The vulnerability is triggered by manipulation of the 'ID' parameter, which is insufficiently sanitized before being used in SQL queries. This flaw allows remote attackers to inject arbitrary SQL commands, potentially enabling unauthorized data retrieval, modification, or deletion within the backend database. The vulnerability does not require any authentication or user interaction, making it accessible to any remote attacker who can reach the affected endpoint. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction required, and partial impact on confidentiality, integrity, and availability. Although no active exploits have been reported, the public disclosure increases the risk of exploitation attempts. The affected product is niche software for managing online music sites, which may be deployed by smaller organizations or niche service providers. The vulnerability's exploitation could lead to unauthorized access to sensitive data such as user information, music catalog details, or administrative configurations, and could disrupt service availability through data manipulation. The lack of official patches necessitates immediate mitigation efforts by administrators. The vulnerability highlights the critical need for secure coding practices, especially input validation and parameterized queries, to prevent injection flaws.

For European organizations using the code-projects Online Music Site 1.0, this vulnerability poses a risk of unauthorized database access and manipulation, potentially leading to data breaches involving user credentials, music content metadata, or administrative settings. This could result in reputational damage, legal liabilities under GDPR for data exposure, and operational disruptions if critical data is altered or deleted. The remote and unauthenticated nature of the exploit increases the attack surface, especially for publicly accessible administrative interfaces. Organizations in the music industry or digital content providers in Europe relying on this software may face targeted attacks aiming to steal intellectual property or disrupt services. The medium severity reflects a balance between ease of exploitation and limited scope of impact, but the absence of patches and public disclosure heighten urgency. Additionally, attackers could leverage the vulnerability as a foothold for further network compromise if the affected system is connected to broader infrastructure. The impact is amplified in countries with strong digital music markets or where the software has higher adoption rates.

1. Immediately restrict access to the /Administrator/PHP/AdminDeleteCategory.php endpoint by IP whitelisting or VPN-only access to reduce exposure. 2. Implement web application firewall (WAF) rules to detect and block SQL injection patterns targeting the 'ID' parameter. 3. Conduct a thorough code review and refactor the vulnerable code to use parameterized SQL queries or prepared statements, ensuring proper input validation and sanitization. 4. If source code modification is not feasible, consider deploying database-level permissions to limit the impact of SQL injection, such as using least-privilege database accounts. 5. Monitor database logs and web server logs for unusual query patterns or repeated failed attempts indicative of exploitation attempts. 6. Engage with the vendor or community to obtain or develop official patches or updates addressing this vulnerability. 7. Educate administrators on secure configuration practices and the risks of exposing administrative interfaces publicly. 8. Regularly back up critical data and verify restoration procedures to mitigate potential data loss from exploitation. 9. Consider network segmentation to isolate the affected application from sensitive backend systems. 10. Stay updated on threat intelligence feeds for any emerging exploits targeting this vulnerability.
