CVE-2026-11490: Online Music Site 1.0 SQLi Vulnerability

CVE-2026-11490 Overview

CVE-2026-11490 is a SQL injection vulnerability in code-projects Online Music Site 1.0. The flaw resides in /Frontend/Search.php, where the Category parameter is passed directly into a SQL query without sanitization. Remote attackers can manipulate the parameter to alter query logic, read database contents, or modify backend records. No authentication or user interaction is required to exploit the issue. The exploit has been publicly disclosed, increasing the likelihood of opportunistic attacks against exposed installations. The weakness is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Unauthenticated remote attackers can inject arbitrary SQL through the Category parameter in Search.php, compromising confidentiality and integrity of the application database.

Technical Details for CVE-2026-11490

Vulnerability Analysis

The vulnerability is a SQL injection issue in the search functionality of Online Music Site 1.0. The script /Frontend/Search.php accepts a user-controlled Category argument and concatenates it into a SQL statement without parameterization or input validation. Attackers can supply crafted values containing SQL metacharacters, including single quotes, comments, and UNION SELECT clauses, to break out of the intended query context. Successful exploitation enables extraction of sensitive data such as user credentials, session identifiers, and stored content. Depending on the privileges of the application database user, it may also allow modification or deletion of records.

Root Cause

The root cause is improper neutralization of user input passed into a SQL query, mapped to [CWE-74]. The application treats the Category request parameter as trusted data and embeds it directly into a query string. There is no use of prepared statements, bound parameters, or input filtering to enforce a safe data type or character set.

Attack Vector

The attack is performed remotely over the network against the public search endpoint. An attacker submits an HTTP request to /Frontend/Search.php with a malicious Category value. Because the endpoint is unauthenticated, exploitation can be automated at scale. The publicly available proof-of-concept lowers the barrier to entry for unsophisticated attackers.

No verified exploit code is included here. Technical details are documented in the GitHub issue for CVE-2026-11490 and the VulDB entry for CVE-2026-11490.

Detection Methods for CVE-2026-11490

Indicators of Compromise

HTTP requests to /Frontend/Search.php containing SQL metacharacters such as ', --, /*, or UNION in the Category parameter
Web server access logs showing repeated requests to Search.php with encoded payloads such as %27, %20OR%20, or 0x literals
Unusual database error messages returned by the application following requests to the search endpoint
Spikes in outbound traffic from the database host correlating with search requests

Detection Strategies

Inspect web server and application logs for Category parameter values that contain SQL keywords or boolean expressions
Deploy a Web Application Firewall (WAF) rule set tuned for SQL injection patterns against the /Frontend/ path
Enable database query logging and alert on syntax errors or query timeouts originating from the application user

Monitoring Recommendations

Forward web, application, and database logs to a centralized analytics platform for correlation
Monitor authentication tables and user records for unauthorized changes or new privileged accounts
Track the rate of failed queries from the application's database account, which often spikes during injection probing

How to Mitigate CVE-2026-11490

Immediate Actions Required

Restrict public access to /Frontend/Search.php until the input handling is remediated, using network controls or a WAF
Rotate database credentials used by the application and audit the database user's privileges, removing write or administrative rights where not required
Review web logs for prior exploitation attempts against the Category parameter and investigate any matches

Patch Information

No vendor patch is referenced in the CVE record. Operators should monitor the code-projects website and the VulDB advisory for CVE-2026-11490 for updates. Until an official fix is available, source-level remediation is required by the application owner.

Workarounds

Replace string concatenation in Search.php with prepared statements using PDO or mysqli bound parameters
Enforce a strict allow-list for the Category value, matching only known category identifiers
Apply server-side input validation that rejects requests containing SQL metacharacters before reaching the database layer
Deploy a WAF rule that blocks SQL injection signatures targeting the Category parameter

bash

# Example WAF rule (ModSecurity) to block SQLi attempts on the Category parameter
SecRule ARGS:Category "@detectSQLi" \
    "id:1026114901,phase:2,deny,status:403,\
    msg:'Possible SQL injection in Category parameter (CVE-2026-11490)',\
