CVE-2026-0850 identifies a SQL injection vulnerability in the code-projects Intern Membership Management System version 1.0, located in the /admin/delete_activity.php script. The vulnerability is triggered by manipulating the 'activity_id' parameter, which is not properly sanitized before being used in SQL queries. This flaw allows an attacker with authenticated high-level privileges to inject malicious SQL code remotely, potentially leading to unauthorized data access, modification, or deletion within the system's database. The vulnerability does not require user interaction but does require the attacker to have high privilege access, which limits exploitation to insiders or compromised accounts with administrative rights. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no user interaction (UI:N), and high privileges required (PR:H). The impact on confidentiality, integrity, and availability is low to moderate, as the attacker can manipulate data but only within the scope of the compromised system. No patches or exploit code are currently publicly available, but the vulnerability has been disclosed, increasing the risk of future exploitation. The affected product is niche software used for managing intern memberships, which may be deployed in organizations with structured internship programs.

For European organizations using the code-projects Intern Membership Management System 1.0, this vulnerability poses a risk of unauthorized data manipulation or leakage within intern membership databases. Potential impacts include exposure of sensitive personal data of interns, unauthorized deletion or modification of activity records, and disruption of membership management operations. Such incidents could lead to regulatory non-compliance under GDPR, reputational damage, and operational inefficiencies. The requirement for high privilege authentication reduces the likelihood of external attackers exploiting this vulnerability directly but raises concerns about insider threats or compromised administrative accounts. Organizations relying heavily on this system for managing intern programs, especially in sectors like education, research, and corporate training, may face increased risk. The medium severity suggests that while the threat is not critical, timely remediation is necessary to prevent escalation or chained attacks.

1. Apply any available patches or updates from the vendor immediately once released. 2. Implement strict input validation and sanitization on the 'activity_id' parameter and other user inputs to prevent SQL injection. 3. Restrict administrative access to the Intern Membership Management System to trusted personnel only, employing the principle of least privilege. 4. Enforce strong authentication mechanisms, such as multi-factor authentication, for all high privilege accounts. 5. Monitor and audit administrative activities and access logs for suspicious behavior indicative of exploitation attempts. 6. Consider deploying Web Application Firewalls (WAF) with SQL injection detection rules tailored to the application. 7. Conduct regular security assessments and code reviews of the membership management system to identify and remediate similar vulnerabilities. 8. Educate administrators about the risks of SQL injection and the importance of secure credential management.
