Summary

CVE-2026-5669 is a medium-severity Injection (CWE-74) vulnerability. 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 13.5th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2026-5669 is a SQL injection vulnerability (CWE-74, CWE-89) in the Cyber-III Student-Management-System up to commit 1a938fa61e9f735078e9b291d2e6215b4942af3f. It affects unknown code in the /login.php file of the Parameter Handler component, where manipulation of the Password argument enables the injection.

The vulnerability is exploitable remotely by unauthenticated attackers (PR:N) with low attack complexity (AC:L) and no user interaction (UI:N). Exploitation can result in low impacts to confidentiality, integrity, and availability (C:L/I:L/A:L), yielding a CVSS 3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).

Due to the product's rolling release model, specific details on affected and updated versions are unavailable. The project was informed early via GitHub issue #240 but has not responded. An exploit has been publicly disclosed, with details available in VULDB entries and the GitHub repository.
