Deeper analysisAI
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.
