CVE-2026-0850 identifies a SQL injection vulnerability in the code-projects Intern Membership Management System version 1.0, specifically in the /admin/delete_activity.php script. The vulnerability arises from insufficient input validation or sanitization of the activity_id parameter, which is used in SQL queries without proper escaping or parameterization. An attacker with high privileges can remotely manipulate this parameter to inject arbitrary SQL commands, potentially allowing unauthorized reading, modification, or deletion of database records. The vulnerability does not require user interaction but does require the attacker to have authenticated access with elevated privileges, which somewhat limits the attack vector. The CVSS 4.0 score of 5.1 reflects a medium severity, considering the ease of remote exploitation but the prerequisite of high privileges. No patches or fixes have been linked yet, and no known exploits are reported in the wild, but the public disclosure increases the likelihood of future exploitation attempts. The vulnerability impacts the confidentiality, integrity, and availability of the membership system's data, which could include sensitive intern or membership information. Organizations using this system should conduct immediate code reviews, implement input validation, and monitor for suspicious database activity to mitigate risks.

The SQL injection vulnerability can lead to unauthorized access to sensitive intern membership data, including personal information and activity logs. Attackers exploiting this flaw could manipulate or delete critical records, undermining data integrity and potentially disrupting membership management operations. This could result in data breaches, loss of trust, regulatory penalties, and operational downtime. Since the vulnerability requires high privileges, the impact is somewhat contained to insiders or compromised accounts with elevated access, but the risk remains significant in environments where privilege escalation is possible. The availability of the system could also be affected if attackers execute destructive SQL commands. Overall, the vulnerability poses a moderate risk to organizations relying on this software for managing intern memberships, especially those handling sensitive or regulated data.

To mitigate CVE-2026-0850, organizations should immediately review and sanitize all inputs to the /admin/delete_activity.php endpoint, particularly the activity_id parameter. Implement parameterized queries or prepared statements to prevent SQL injection. Restrict access to administrative functions strictly to trusted users and enforce the principle of least privilege to minimize the risk of exploitation by insiders. Conduct thorough code audits to identify and remediate similar vulnerabilities elsewhere in the application. Monitor database logs for unusual queries or patterns indicative of injection attempts. If a patch becomes available from the vendor, apply it promptly. Additionally, consider deploying web application firewalls (WAFs) with SQL injection detection rules as a temporary protective measure. Educate administrators about secure coding practices and the risks of SQL injection to prevent recurrence.
