Summary
CVE-2026-2223 is a medium-severity Injection (CWE-74) vulnerability in Fabian Online Reviewer 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 34.7th 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 SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-2223 is a SQL injection vulnerability affecting code-projects Online Reviewer System 1.0, published on 2026-02-09. The issue resides in an unknown functionality of the file /system/system/students/assessments/pretest/take/index.php, where manipulation of the ID argument enables SQL injection. It is associated with CWE-74 and CWE-89, and 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 lack of prerequisites.
The vulnerability can be exploited remotely by unauthenticated attackers with low complexity and no user interaction required. Successful exploitation allows limited impacts on confidentiality, integrity, and availability, potentially enabling unauthorized data access, modification, or disruption through injected SQL queries via the ID parameter.
Advisories and details are available from sources including code-projects.org, a GitHub issue at github.com/tiancesec/CVE/issues/24, and VulDB entries at vuldb.com/?ctiid.344940, vuldb.com/?id.344940, and vuldb.com/?submit.750027. The exploit has been publicly disclosed and may be used by attackers.
In notable context, the public disclosure of the exploit increases the risk of real-world exploitation against unpatched instances of the affected software.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of untrusted inputs such as the ID parameter to block SQL injection payloads before they reach the database.
Mandates timely remediation of known vulnerabilities in the exposed index.php endpoint, eliminating the SQL injection flaw once a patch or code fix is applied.
Enforces least-privilege database accounts so that even a successful injection via the ID argument yields only limited confidentiality/integrity/availability impact.
