CVE-2026-78057: Student Management System SQL Injection Flaw

CVE-2026-78057 Overview

CVE-2026-78057 is a SQL injection vulnerability in the sambitraj Student-Management-System project, affecting code up to commit 56ba287f2e9031523ccb4244cb6e3fe530e4e5d5. The flaw resides in the Management Mutation Handler component, where the roll_no, name, father_name, class, mobile, email, password, and remark arguments are concatenated into database queries without proper sanitization. Remote attackers with low-level privileges can manipulate these parameters to execute arbitrary SQL statements. The exploit has been publicly disclosed. Because the project follows a rolling release strategy, no fixed version has been designated, and the maintainer has not yet responded to the issue report.

Critical Impact
Authenticated remote attackers can inject SQL statements through multiple input fields in the Management Mutation Handler, leading to unauthorized read, modification, or destruction of student records stored in the backend database.

Technical Details for CVE-2026-78057

Vulnerability Analysis

The vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component). The Management Mutation Handler processes user-supplied data from student management operations and passes those values directly into SQL statements. Attackers can craft input containing SQL metacharacters to break query context and append arbitrary clauses.

Exploitation requires network access and low authentication, but no user interaction. Because the affected parameters cover a broad set of student attributes such as roll_no, email, and password, attackers have multiple injection points to enumerate schema, exfiltrate records, or tamper with authentication data.

Root Cause

The root cause is missing parameterization of SQL queries within the mutation handler. Input values from HTTP requests are interpolated into query strings rather than bound through prepared statements. This allows attacker-controlled data to be interpreted as SQL syntax by the database engine.

Attack Vector

A remote attacker with a valid low-privileged session sends a crafted mutation request. The malicious payload is placed in any of the vulnerable arguments including roll_no, name, father_name, class, mobile, email, password, or remark. The server forwards the tainted string to the database, which executes the injected SQL. Public exploit details are available in the GitHub Issue #5 Discussion and VulDB CVE-2026-78057 references.

No verified proof-of-concept code is reproduced here. Technical details for the injection points are described in the referenced advisories.

Detection Methods for CVE-2026-78057

Indicators of Compromise

Unexpected SQL metacharacters such as single quotes, UNION, --, or /* in HTTP request parameters targeting student mutation endpoints.
Database error messages returned in application responses referencing syntax errors on the affected columns.
Anomalous read volumes or modifications on student tables that do not correspond to normal administrative activity.

Detection Strategies

Deploy web application firewall rules that inspect mutation requests for SQL injection patterns across the eight affected arguments.
Enable database query logging and alert on queries whose structure deviates from the application's known query templates.
Correlate authenticated user sessions with query-error spikes to surface accounts probing the mutation handler.

Monitoring Recommendations

Monitor HTTP POST bodies to Management Mutation Handler endpoints for high-entropy or SQL-keyword-heavy values in the vulnerable fields.
Track authentication events preceding suspicious mutation calls to identify credential abuse feeding the injection.
Retain application and database audit logs for retrospective hunting once further indicators are published.

How to Mitigate CVE-2026-78057

Immediate Actions Required

Restrict access to the Student-Management-System deployment to trusted networks until a patched commit is available.
Disable or gate the Management Mutation Handler routes behind an authenticating reverse proxy that enforces strict input validation.
Rotate credentials for any account with write access to the application, and review database logs for evidence of prior exploitation.

Patch Information

No official fix has been released. The project uses a rolling release model, and the maintainer has not responded to the disclosure issue as of the last NVD update on 2026-08-24. Track the upstream GitHub Student Management System repository and the GitHub Issue #5 Discussion for remediation updates.

Workarounds

Refactor affected queries locally to use parameterized statements or prepared bindings for all eight vulnerable arguments.
Add server-side allowlist validation for roll_no, mobile, email, and class inputs to reject non-conforming characters.
Place the application behind a WAF with SQL injection signatures enabled for the mutation endpoints.
Enforce least-privilege database accounts so the application user cannot alter schema or read sensitive tables beyond its scope.
