CVE-2026-0569 Overview
A SQL injection vulnerability has been discovered in code-projects Online Music Site version 1.0. This vulnerability affects the /Frontend/AlbumByCategory.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. The attack can be executed remotely without authentication, potentially exposing sensitive database contents, enabling data manipulation, or compromising the underlying system.
Critical Impact
Unauthenticated attackers can exploit this SQL injection vulnerability remotely to access, modify, or delete database contents, potentially leading to data breach or complete system compromise.
Affected Products
- code-projects Online Music Site 1.0
- /Frontend/AlbumByCategory.php endpoint

Technical Details for CVE-2026-0569
Vulnerability Analysis
This SQL injection vulnerability exists in the AlbumByCategory.php file within the Frontend directory of the Online Music Site application. The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where user-controlled input is improperly incorporated into commands or queries.
The vulnerable endpoint accepts an ID parameter that is directly incorporated into database queries without proper sanitization or parameterization. This allows attackers to craft malicious input that modifies the intended SQL query structure, enabling unauthorized database operations.
Root Cause
The root cause of this vulnerability is the lack of input validation and parameterized queries in the AlbumByCategory.php file. The application directly concatenates user-supplied input from the ID parameter into SQL queries, allowing attackers to break out of the intended query context and execute arbitrary SQL commands.
This is a classic example of insufficient input sanitization combined with dynamic SQL query construction, a common pattern in legacy PHP applications that do not leverage prepared statements or ORM frameworks.
Attack Vector
The attack vector is network-based, requiring no authentication or user interaction. An attacker can exploit this vulnerability by sending crafted HTTP requests to the /Frontend/AlbumByCategory.php endpoint with a malicious ID parameter value containing SQL injection payloads.
The exploitation technique involves injecting SQL syntax through the ID parameter to manipulate query behavior. Common attack patterns include UNION-based injection to extract data from other tables, boolean-based blind injection to infer database contents, time-based blind injection for scenarios where direct output is not visible, and stacked queries for data modification or privilege escalation.
Additional technical details and proof-of-concept information can be found in the GitHub CVE Issue Discussion and VulDB #339381.
Detection Methods for CVE-2026-0569
Indicators of Compromise
- Unusual SQL syntax patterns in web server access logs targeting /Frontend/AlbumByCategory.php
- HTTP requests containing SQL keywords such as UNION, SELECT, OR 1=1, or comment sequences (--, /**/) in the ID parameter
- Database error messages in application logs indicating malformed queries
- Unexpected database queries or connections originating from the web application
Detection Strategies
- Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the ID parameter
- Implement application-level logging to capture all requests to AlbumByCategory.php with parameter values
- Configure database audit logging to identify suspicious query patterns or unauthorized data access
- Use runtime application self-protection (RASP) solutions to detect SQL injection attempts in real-time
Monitoring Recommendations
- Monitor access logs for requests to /Frontend/AlbumByCategory.php containing encoded characters or SQL syntax
- Set up alerts for database errors related to query syntax issues from the web application
- Track failed authentication attempts and unusual data access patterns that may indicate post-exploitation activity
How to Mitigate CVE-2026-0569
Immediate Actions Required
- Restrict or disable access to /Frontend/AlbumByCategory.php until a patch is applied
- Implement WAF rules to filter SQL injection payloads targeting the ID parameter
- Review and audit database access logs for signs of prior exploitation
- Consider taking the affected application offline if exposure is critical
Patch Information
No official vendor patch has been identified for this vulnerability. The application is a code-projects educational project, and users should implement manual remediation by modifying the source code to use parameterized queries or prepared statements.
For reference, consult the Code Projects Resource for any available updates. The vulnerability details are tracked in VulDB Submission #729252.
Workarounds
- Implement input validation to whitelist only numeric values for the ID parameter
- Refactor the vulnerable code to use prepared statements with parameterized queries
- Deploy a reverse proxy or WAF with SQL injection detection capabilities in front of the application
- Restrict database user privileges to limit potential damage from successful exploitation
To remediate the SQL injection vulnerability, modify the PHP code in AlbumByCategory.php to use prepared statements. Replace any direct query concatenation with PDO or MySQLi prepared statements, ensuring the ID parameter is bound as an integer type. Additionally, implement strict input validation to verify that the ID parameter contains only numeric characters before processing.
