CVE-2026-0850 identifies a SQL injection vulnerability in the code-projects Intern Membership Management System version 1.0, specifically within the /admin/delete_activity.php script. The vulnerability arises from improper sanitization of the activity_id parameter, which is used in SQL queries without adequate validation or parameterization. This flaw allows an authenticated attacker with high privileges to inject arbitrary SQL commands remotely, potentially manipulating the database. The impact includes unauthorized data disclosure, data modification, or deletion, which compromises confidentiality, integrity, and availability of the system's data. The vulnerability does not require user interaction but does require the attacker to have authenticated access with elevated privileges, limiting the attack surface to insiders or compromised accounts. Although no known exploits are currently active in the wild, the public disclosure increases the risk of exploitation by threat actors. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no user interaction (UI:N), but requires high privileges (PR:H). The vulnerability affects only version 1.0 of the product, and no official patches have been linked yet. This vulnerability is significant for organizations relying on this membership management system, as it could lead to unauthorized administrative actions and data breaches.

For European organizations using the code-projects Intern Membership Management System 1.0, this vulnerability poses a risk of unauthorized access to sensitive membership data, manipulation or deletion of activity records, and potential disruption of membership management operations. The SQL injection could allow attackers to extract confidential information, alter membership statuses, or corrupt data integrity, impacting organizational trust and compliance with data protection regulations such as GDPR. The requirement for authenticated high-privilege access reduces the likelihood of external exploitation but increases the threat from insider attacks or compromised credentials. Disruption of membership management could affect operational continuity, member communications, and event management. Organizations in sectors with strict data privacy requirements or those managing large member databases are particularly vulnerable. The absence of known exploits in the wild currently limits immediate risk but does not eliminate it, especially as public disclosure may lead to exploit development.

Organizations should immediately audit and restrict access to the /admin/delete_activity.php functionality, ensuring only trusted, authenticated administrators have access. Implement strict input validation and parameterized queries or prepared statements to prevent SQL injection. Monitor logs for unusual activity related to the activity_id parameter or administrative actions. Apply any available patches or updates from the vendor as soon as they are released. If patches are not yet available, consider deploying web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. Conduct regular credential audits and enforce strong authentication mechanisms to reduce the risk of compromised high-privilege accounts. Additionally, perform security awareness training for administrators to recognize phishing or social engineering attempts that could lead to credential compromise. Finally, maintain regular backups of membership data to enable recovery in case of data corruption or deletion.
