CVE-2026-11490: SQL Injection in code-projects Online Music Site 1.0

Technical summary

CVE-2026-11490 is a remote SQL injection vulnerability affecting the /Frontend/Search.php endpoint in code-projects Online Music Site 1.0. The Category argument is processed without sufficient input sanitization or parameterized query protection, allowing attackers to inject arbitrary SQL syntax. The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output) and CWE-89 (SQL Injection). With a CVSS 3.1 score of 7.3 (HIGH severity), it carries a network-based attack vector, low complexity, and no privilege or user interaction requirements. The attack surface includes confidentiality, integrity, and availability impacts at low scope.

Business impact

This vulnerability poses a direct threat to database security and application availability. Attackers can extract sensitive user data (credentials, personal information, music preferences), modify or delete records, or disrupt service availability through resource-exhaustive queries. For a music streaming platform, this could lead to user trust erosion, regulatory exposure (data protection laws), and operational downtime. Given that public exploits are available, the risk of opportunistic attacks is elevated.

Affected systems

code-projects Online Music Site version 1.0 is the confirmed affected product. Organizations running this version in production should assume they are exposed. The vulnerability does not require special network conditions, authentication, or client-side interaction—any internet-connected instance is at risk. End-of-life status of this product version should be verified with the vendor.

Exploitability

Exploitability is high. The attack vector is network-based with low complexity, meaning standard HTTP requests suffice. No credentials, special privileges, or user interaction are required. The public disclosure of exploit code further lowers the barrier to attack. Automated scanning tools can identify vulnerable instances, and attack execution is straightforward enough for moderately skilled threat actors.

Remediation

Immediate patching is the primary remediation step. Contact code-projects to obtain a patched version that implements parameterized queries or prepared statements for the Category parameter. If patching is delayed, implement a Web Application Firewall (WAF) with SQL injection signatures to block malicious payloads, restrict database user permissions to principle of least privilege, and segment the database from general network access. Input validation at the application layer should enforce strict allowlists for Category values.

Patch guidance

Verify the latest security advisory from code-projects for the patched version number and apply it immediately to all instances running version 1.0. Test patches in a staging environment before production deployment. If the vendor has not released a patch, escalate to the vendor for timeline and interim mitigation options. Monitor vendor security channels for updates.

Detection guidance

Monitor application logs and WAF logs for SQL injection patterns in the Category parameter (e.g., single quotes, UNION keywords, SQL comments). Search for POST/GET requests to /Frontend/Search.php with suspicious Category values. Endpoint Detection and Response (EDR) tools can flag unusual database query patterns or elevated database access. Network intrusion detection systems should flag payloads matching known SQL injection signatures for CVE-2026-11490.

Why prioritize this

This vulnerability merits immediate attention due to its HIGH CVSS score (7.3), public exploit availability, and unauthenticated remote attack vector. SQL injection directly compromises data confidentiality, integrity, and availability. Organizations running the affected version should patch or implement compensating controls within 24–48 hours.

Risk score, explained

The CVSS 3.1 score of 7.3 reflects a network-accessible SQL injection with low attack complexity, no authentication requirement, and multi-faceted impact (C:L, I:L, A:L). The score is elevated by the broad attack surface (any internet user) and the availability of public exploit code, which reduces attack difficulty in practice despite the CVSS AC:L rating. The lack of scope expansion (S:U) prevents an even higher score.
