The vulnerability identified as CVE-2026-26694 affects the Simple Student Alumni System version 1.0 developed by code-projects. It is an SQL Injection flaw located in the /TracerStudy/modal_view.php script. SQL Injection (CWE-89) vulnerabilities occur when user-supplied input is improperly sanitized and directly included in SQL queries, allowing attackers to manipulate the database queries executed by the application. In this case, the vulnerability allows unauthenticated remote attackers to inject malicious SQL commands without any user interaction or privileges. The CVSS v3.1 base score of 9.8 reflects the critical nature of this issue, with attack vector being network (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and impacts on confidentiality (C:H), integrity (I:H), and availability (A:H). Exploiting this vulnerability could lead to unauthorized disclosure of sensitive student and alumni data, data tampering, deletion, or even full system compromise if the database is critical to application functionality. No patches or fixes have been published yet, and no known exploits are currently in the wild, but the vulnerability's characteristics make it a prime target for attackers once exploit code becomes available. The affected software is likely used by educational institutions to manage student and alumni information, making the data valuable and sensitive. The vulnerability highlights the need for secure coding practices such as using prepared statements, parameterized queries, and rigorous input validation to prevent injection attacks.

The impact of CVE-2026-26694 is severe for organizations using the Simple Student Alumni System v1.0. Successful exploitation can lead to complete compromise of the backend database, exposing sensitive personal information of students and alumni, including potentially personally identifiable information (PII). Data integrity can be compromised by unauthorized modification or deletion of records, which could disrupt institutional operations and damage trust. Availability of the system may also be affected if attackers execute destructive queries or cause denial of service conditions. The breach of confidentiality and integrity can lead to regulatory compliance violations, legal liabilities, and reputational damage. Since the vulnerability requires no authentication or user interaction, it can be exploited remotely and at scale, increasing the risk of widespread attacks. Educational institutions, alumni associations, and related organizations worldwide that rely on this software are at risk of data breaches and operational disruption.

To mitigate this vulnerability, organizations should immediately review and update the affected application code to use parameterized queries or prepared statements instead of directly embedding user input in SQL commands. Implement strict input validation and sanitization for all user-supplied data, especially in the /TracerStudy/modal_view.php endpoint. If source code modification is not immediately possible, consider deploying web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this endpoint. Monitor database logs and application logs for unusual query patterns or errors indicative of injection attempts. Restrict database user permissions to the minimum necessary to limit the impact of a successful injection. Additionally, organizations should stay alert for official patches or updates from the software vendor and apply them promptly once available. Conduct security assessments and penetration testing to identify and remediate similar injection flaws in other parts of the application. Educate developers on secure coding practices to prevent future injection vulnerabilities.
