CVE-2026-0569 identifies a SQL injection vulnerability in the code-projects Online Music Site version 1.0, specifically within the /Frontend/AlbumByCategory.php file. The vulnerability is triggered by manipulation of the 'ID' parameter, which is not properly sanitized or validated before being used in SQL queries. This flaw allows remote attackers to inject arbitrary SQL commands without requiring authentication or user interaction, enabling them to access, modify, or delete database information. The CVSS 4.0 score is 6.9 (medium severity), reflecting the network attack vector, low complexity, no privileges or user interaction needed, and partial impact on confidentiality, integrity, and availability. Although no exploits have been observed in the wild, the public disclosure increases the risk of exploitation. The vulnerability affects only version 1.0 of the product, which is a niche online music platform software. The lack of official patches or mitigation guidance increases the urgency for organizations to implement defensive coding practices or temporary workarounds. The vulnerability could be leveraged to extract sensitive user data, alter music catalog information, or disrupt service availability, impacting both users and operators of the platform.

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 data and services. Attackers could remotely exploit the SQL injection to access sensitive customer information, including user credentials or payment data, potentially leading to data breaches and regulatory non-compliance under GDPR. Integrity of the music catalog or user data could be compromised, resulting in unauthorized content modification or deletion. Availability may also be affected if attackers execute destructive SQL commands, causing service outages. The impact is particularly critical for digital media companies, online music retailers, or cultural institutions relying on this software. Additionally, reputational damage and financial losses from remediation and potential fines could be substantial. The medium severity rating suggests that while the vulnerability is not trivial, it is exploitable without complex conditions, warranting prompt attention.

Since no official patches are currently available for CVE-2026-0569, European organizations should implement immediate mitigations to reduce risk. First, apply strict input validation and sanitization on the 'ID' parameter in /Frontend/AlbumByCategory.php, ensuring only expected numeric or predefined values are accepted. Refactor the code to use parameterized queries or prepared statements to prevent SQL injection. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection payloads targeting this endpoint. Conduct thorough code audits of similar input handling throughout the application. Monitor logs for suspicious query patterns or repeated access attempts to the vulnerable endpoint. If feasible, isolate or restrict access to the affected service until a secure version or patch is released. Educate developers on secure coding practices to prevent future injection flaws. Finally, maintain up-to-date backups to enable recovery in case of data corruption or loss.
