Deeper analysis

CVE-2026-37339, published on 2026-04-16, is a critical SQL injection vulnerability (CWE-89) in SourceCodester Simple Music Cloud Community System version 1.0. The flaw resides in the file /music/view_genre.php, where user-supplied input is not properly sanitized, allowing malicious SQL payloads to be injected into backend database queries. It carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating a high-severity issue due to its ease of exploitation and severe potential impacts.

Remote attackers require no authentication or privileges and can exploit the vulnerability over the network with low complexity and no user interaction. Successful injection enables arbitrary SQL command execution, potentially allowing attackers to extract sensitive data such as user credentials or music metadata, modify database contents, delete records, or cause denial of service by corrupting the database.

Mitigation details and a proof-of-concept are documented in the reference advisory at https://github.com/mt-0505/cve-report/blob/main/sourcecodester/simple-music-cloud-community-system/SQL-3.md. Security practitioners should review this for reproduction steps and apply input validation, prepared statements, or upgrade to a patched version if available.

Affected Assets

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

prevent

SI-10 requires validation of user-supplied inputs like those in /music/view_genre.php to prevent SQL injection by ensuring malicious payloads are rejected or sanitized before reaching database queries.

prevent

SI-9 enforces restrictions on information inputs to block SQL injection payloads in the unauthenticated view_genre.php endpoint by limiting input types, lengths, or characters.

prevent

SI-2 mandates timely identification and remediation of flaws like the SQL injection in /music/view_genre.php through patching or code fixes such as prepared statements.
