CVE-2026-11530: SQL Injection in imvks786 Student Management System Login

Technical summary

The vulnerability resides in the login functionality (/index.ph) of the student management system, where user-supplied input from the 'usr' and 'pwd' parameters is not properly sanitized before being used in SQL queries. This classic SQL injection flaw (CWE-89) combined with improper input validation (CWE-74) allows attackers to craft malicious payloads that bypass authentication or extract database contents. The product uses a rolling release model, which complicates version tracking and patch identification. As of the last update, the vendor has not publicly responded to the disclosure.

Business impact

A successful exploit could allow unauthorized access to student records, compromising personally identifiable information (PII) and educational data. This exposure creates liability under regulations like FERPA and GDPR, potential reputational damage, and operational disruption. Educational institutions using this system face direct risk to their data governance and student privacy obligations. The public availability of exploit code increases the likelihood of opportunistic attacks targeting deployed instances.

Affected systems

The imvks786 student management system up to commit 9599b560ad3c3b83e75d328b76bedcd489ef1f46 is affected. Exact version numbers are not available due to the rolling release model. Any installation of this system using the vulnerable codebase is at risk. Organizations must consult the project repository or vendor communications to determine their specific exposure.

Exploitability

This vulnerability is highly exploitable. It requires no authentication, no user interaction, and only network access—all conditions typically met in production deployments. The CVSS 3.1 score of 7.3 (High) reflects the combination of remote network attack vector, low complexity, and impact to confidentiality, integrity, and availability. The public availability of exploit code further reduces the barrier to exploitation, making opportunistic and targeted attacks probable.

Remediation

Immediate remediation requires identifying and updating to a patched version of the student management system. Since the project uses rolling releases, consult the imvks786 repository on GitHub or the vendor's security advisory for the specific commit or version that addresses this issue. For organizations unable to update immediately, implement network segmentation to restrict access to the login interface and apply a Web Application Firewall (WAF) rule to block SQL injection patterns in the usr/pwd parameters.

Patch guidance

Check the imvks786 student_management_system repository for commits after 9599b560ad3c3b83e75d328b76bedcd489ef1f46 that address SQL injection in the login component. Deploy any available security patches or updates from the vendor. Given the rolling release model, monitor the project's issue tracker and commit history for confirmation that the vulnerability has been fixed. Implement parameterized queries and prepared statements to prevent future SQL injection issues.

Detection guidance

Monitor authentication logs for unusual login attempts with SQL metacharacters (single quotes, semicolons, SQL keywords like 'UNION', 'OR', etc.) in the username or password fields. Deploy a WAF to detect and block SQL injection patterns. Use database activity monitoring to identify unexpected queries or attempts to access unauthorized tables. Set alerts on failed login attempts from the same source IP, which may indicate SQL injection scanning or exploitation attempts.

Why prioritize this

This vulnerability should be prioritized as HIGH due to its remotely exploitable nature, lack of authentication requirement, public exploit availability, and direct impact on sensitive educational data. The combination of ease of exploitation and business criticality in educational settings demands swift remediation to prevent data breaches and regulatory violations.

Risk score, explained

The CVSS 3.1 score of 7.3 reflects a High-severity vulnerability with critical attack characteristics: remote network-based attack vector (AV:N), low attack complexity (AC:L), no privilege requirements (PR:N), and no user interaction needed (UI:N). The impact includes loss of confidentiality, integrity, and availability (C:L/I:L/A:L), making this a material risk to any organization running the affected system. Public exploit availability increases practical risk beyond the base score.
