CVE-2026-11489: Online Music Site 1.0 SQLi Vulnerability

CVE-2026-11489 Overview

CVE-2026-11489 is a SQL injection vulnerability affecting code-projects Online Music Site 1.0. The flaw resides in the /Administrator/PHP/AdminDeleteAlbum.php script, where the ID parameter is passed directly into a database query without proper sanitization. Remote attackers can manipulate the parameter to inject arbitrary SQL statements. According to the public disclosure, a working exploit has been released, lowering the barrier for opportunistic attacks against exposed instances. The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output).

Critical Impact
Unauthenticated remote attackers can inject SQL through the ID parameter of AdminDeleteAlbum.php, enabling unauthorized read, modification, or deletion of records within the application database.

Technical Details for CVE-2026-11489

Vulnerability Analysis

The vulnerability exists in the administrative album deletion endpoint of code-projects Online Music Site 1.0. The AdminDeleteAlbum.php script accepts an ID argument and concatenates it into a SQL DELETE or SELECT statement without parameterized queries or input validation. Because the script is reachable over the network and the disclosure indicates no authentication barrier is enforced, an attacker can supply crafted payloads in the ID argument to alter the SQL query logic. Successful exploitation results in unauthorized interaction with the backing database, including data extraction through UNION-based or boolean-based techniques and destructive operations through stacked queries where the database driver permits them.

Root Cause

The root cause is improper neutralization of user-supplied input passed to a SQL interpreter [CWE-74]. The ID parameter received by AdminDeleteAlbum.php is incorporated into a dynamic SQL statement without prepared statements, parameter binding, or type casting. PHP scripts that build queries through string concatenation with $_GET or $_POST values exhibit this pattern, and the public disclosure on the GitHub CVE issue confirms this design flaw.

Attack Vector

The attack is performed remotely over the network without authentication or user interaction. An attacker submits an HTTP request to /Administrator/PHP/AdminDeleteAlbum.php with a malicious ID parameter containing SQL metacharacters such as single quotes, comments, or UNION clauses. The injected SQL is executed by the database engine in the context of the application's database user. A public proof-of-concept is referenced in the VulDB advisory for CVE-2026-11489, which documents the exploit string and reproduction steps.

No verified code examples are available. Refer to the linked GitHub CVE issue for the published proof-of-concept and reproduction details.

Detection Methods for CVE-2026-11489

Indicators of Compromise

HTTP requests to /Administrator/PHP/AdminDeleteAlbum.php containing SQL metacharacters in the ID parameter, such as ', --, UNION, SLEEP(, or OR 1=1.
Web server access logs showing repeated ID parameter variations from a single source address.
Database error messages in application logs referencing syntax errors near the ID value.
Unexpected DELETE operations against the albums table or related administrative tables.

Detection Strategies

Deploy web application firewall (WAF) signatures that flag SQL injection patterns targeting the ID parameter on administrative PHP endpoints.
Enable database query logging and alert on queries containing tautologies, UNION SELECT clauses, or stacked statements originating from the music site application user.
Correlate authentication-less access to /Administrator/ paths with subsequent database anomalies.

Monitoring Recommendations

Monitor outbound traffic from the database host for unexpected data egress that may indicate exfiltration via blind SQL injection.
Track query execution time anomalies that could indicate time-based blind SQL injection probes.
Audit administrative endpoint access in web server logs and alert when unauthenticated sessions reach /Administrator/PHP/ routes.

How to Mitigate CVE-2026-11489

Immediate Actions Required

Restrict access to the /Administrator/ directory using HTTP authentication, IP allowlists, or network segmentation until a code fix is applied.
Take the application offline if it is internet-exposed and not behind an authenticated reverse proxy.
Review database and web server logs for prior exploitation attempts referencing AdminDeleteAlbum.php.
Rotate database credentials and audit recently modified or deleted rows in administrative tables.

Patch Information

No official vendor patch has been published for code-projects Online Music Site 1.0 at the time of disclosure. Operators should consult the code-projects website for updates and apply source-level fixes by replacing dynamic SQL construction with PHP Data Objects (PDO) prepared statements or mysqli parameterized queries. Cast the ID parameter to an integer before use where the schema allows.

Workarounds

Implement a WAF rule that rejects requests to AdminDeleteAlbum.php containing non-numeric characters in the ID parameter.
Apply a server-side input filter that enforces ID as an integer using intval() or filter_input(INPUT_GET, 'ID', FILTER_VALIDATE_INT) before any SQL interaction.
Run the database under a least-privilege account that lacks DROP, ALTER, and cross-database SELECT permissions.
Disable the administrative interface entirely if album management is not actively required.

bash

# Example Apache configuration restricting access to the administrative directory
<Location "/Administrator/">
    Require ip 10.0.0.0/8
    Require ip 192.168.0.0/16
</Location>

# Example nginx rule to block non-numeric ID parameters
location ~ ^/Administrator/PHP/AdminDeleteAlbum\.php$ {
    if ($arg_ID !~ ^[0-9]+$) {
        return 403;
    }
