School Management System SQL injection, unauthenticated (CVE-2026-6595)

Vendor-confirmed - CVE-2026-6595 is a high-severity SQL injection in ProjectsAndPrograms School Management System (commits up to 6b6f5426044f89c08d0dd101c7fa71f9042a59) that lets unauthenticated attackers remotely execute arbitrary SQL commands to read, modify, or delete sensitive database records. A public exploit is available, raising immediate risk.

Overview

A high-severity SQL injection vulnerability has been confirmed in the ProjectsAndPrograms School Management System. Tracked as CVE-2026-6595, this flaw allows unauthenticated attackers to execute arbitrary SQL commands remotely. The vendor uses a rolling release model, making specific version numbers unavailable, but the issue is present in commits up to hash 6b6fae5426044f89c08d0dd101c7fa71f9042a59.

Vulnerability Details

The vulnerability exists in the buslocation.php file. Specifically, the bus_id parameter passed via an HTTP GET request is not properly sanitized before being used in a database query. This lack of input validation allows an attacker to inject malicious SQL code. The attack can be launched remotely without any authentication (privileges required: NONE) and does not require any interaction from a system user.

Impact and Risk

Successful exploitation of this SQL injection could allow attackers to read, modify, or delete sensitive data stored in the application’s database. For a school management system, this likely includes student records, staff information, financial data, and other confidential operational details. A public exploit is available, significantly increasing the risk of attempted attacks, though it is not currently confirmed on the CISA Known Exploited Vulnerabilities (KEV) catalog. Organizations should treat this as a high-priority issue.

Remediation and Mitigation

The product vendor was contacted prior to disclosure but did not respond. Given the rolling release delivery model, users must take immediate action.

Primary Action: Administrators should check with the vendor or project maintainers for the latest patched version or commit that addresses this issue in buslocation.php and update immediately. Since the vendor has not provided guidance, consider the following mitigations if an immediate update is not possible:

• Apply a Web Application Firewall (WAF) rule to block SQL injection patterns targeting the bus_id parameter.
• If feasible, restrict network access to the management system’s web interface to trusted IP ranges only.
• Monitor database and application logs for unusual query patterns or unauthorized access attempts.

Organizations should also review their breach detection capabilities, as successful exploitation could lead to a data incident. For context on how such vulnerabilities lead to real-world incidents, you can review recent breach reports.

Security Insight

This vulnerability highlights the persistent risk in widely used administrative software that handles highly sensitive data. The lack of vendor response and the public availability of an exploit create a dangerous window for attackers. It mirrors a common pattern where niche but critical software becomes a target once a proof-of-concept is released, emphasizing the need for proactive community-driven patching when official vendor support is absent.
