CVE-2026-1176 is a medium-severity Injection (CWE-74) vulnerability in Itsourcecode School Management System. Its CVSS base score is 6.9 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SC-7 (Boundary Protection).
Deeper analysis
CVE-2026-1176 is a SQL injection vulnerability (CWE-74, CWE-89) in the itsourcecode School Management System 1.0. The issue resides in an unknown function within the file /subject/index.php, where manipulation of the ID argument enables SQL injection. Published on 2026-01-19, it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L), indicating high severity due to its network accessibility and ease of exploitation.
Unauthenticated remote attackers can exploit this vulnerability with low complexity and no user interaction required. By injecting malicious payloads via the ID parameter, attackers may achieve limited impacts on confidentiality, integrity, and availability, such as unauthorized data access, modification, or denial of service against the database.
Advisories from VulDB (ctiid.341770, id.341770, submit.736477) and a GitHub issue (ltranquility/CVE/issues/32) document the flaw, with the vendor site at itsourcecode.com. No specific patches or mitigation steps are detailed in the disclosure, so practitioners should monitor these references for updates and apply input validation or parameterized queries to the affected endpoint.
The exploit has been publicly released, heightening the risk of immediate real-world attacks against exposed instances of the system.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of the ID parameter in /subject/index.php to block malicious SQL payloads before they reach the database.
Boundary protection devices such as WAF rules can inspect and drop SQL injection attempts targeting the exposed subject/index.php endpoint.
System monitoring can identify anomalous SQL syntax or error patterns originating from unauthenticated requests to the vulnerable ID parameter.
