Deeper analysis
CVE-2026-2198 is a SQL injection vulnerability (CWE-74, CWE-89) affecting code-projects Online Reviewer System 1.0. The flaw exists in an unknown function of the file /system/system/admins/assessments/pretest/loaddata.php, where manipulation of the difficulty_id argument enables the injection. Published on 2026-02-09, it has 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).
Unauthenticated attackers with network access can exploit this remotely with low complexity and no user interaction required. Successful exploitation grants limited impacts on confidentiality, integrity, and availability, such as reading or modifying small amounts of data or causing minor disruptions. A public exploit is available and might be used.
Mitigation details are covered in advisories at VulDB (ctiid.344901, id.344901, submit.750017), a GitHub issue from tiancesec/CVE/issues/19, and the project site at code-projects.org. Security practitioners should consult these for patching or workaround guidance.
The public availability of the exploit elevates the risk of real-world exploitation in unpatched deployments of this system.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of the difficulty_id input parameter to block SQL injection payloads in loaddata.php.
Enforces access-control decisions on the /admins/assessments/pretest/ path so that unauthenticated remote callers cannot reach or manipulate the vulnerable function.
Enables monitoring and analysis of HTTP requests and database queries to identify anomalous difficulty_id values indicative of active SQL injection attempts.
