CVE-2026-0699 identifies a SQL injection vulnerability in the code-projects Intern Membership Management System version 1.0. The vulnerability is located in the /intern/admin/edit_activity.php script, specifically involving the activity_id parameter. An attacker with high privileges can remotely manipulate this parameter to inject malicious SQL queries into the backend database. This injection flaw allows unauthorized access or modification of database contents, potentially leading to data leakage, corruption, or denial of service. The vulnerability does not require user interaction but does require the attacker to have high-level privileges, which somewhat limits the attack surface. The CVSS 4.0 score is 5.1 (medium severity), reflecting the moderate impact and exploitation complexity. No patches or fixes have been linked yet, and while no active exploitation in the wild is reported, public exploit code availability increases the risk of future attacks. The vulnerability affects only version 1.0 of this specific membership management system, which is likely used in limited organizational contexts. The lack of scope change and absence of user interaction reduce the overall severity, but the direct database manipulation risk remains significant for affected deployments.

The primary impact of this vulnerability is unauthorized access and manipulation of the backend database of the Intern Membership Management System. Successful exploitation could lead to exposure of sensitive membership data, unauthorized modification or deletion of records, and potential disruption of membership management operations. This compromises confidentiality, integrity, and availability of the system. Organizations relying on this software for managing intern memberships or related activities could face data breaches, loss of trust, and operational downtime. Since the exploit requires high privileges, the risk is somewhat mitigated by internal access controls, but insider threats or compromised privileged accounts could still lead to exploitation. The public availability of exploit code increases the likelihood of attacks, especially in environments where patching is delayed or absent. The limited scope of affected versions and product adoption means the global impact is contained but critical for affected organizations.

Organizations using code-projects Intern Membership Management System version 1.0 should immediately review and restrict access to the /intern/admin/edit_activity.php functionality to trusted administrators only. Implement strict input validation and parameterized queries or prepared statements to prevent SQL injection on the activity_id parameter. If possible, upgrade to a patched version once available or apply vendor-provided fixes promptly. In the absence of patches, consider deploying web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this endpoint. Conduct regular audits of privileged accounts to minimize risk of insider exploitation. Monitor logs for suspicious activity related to the edit_activity.php script and the activity_id parameter. Educate administrators about the risks of SQL injection and enforce the principle of least privilege to reduce attack surface. Finally, maintain regular backups of membership data to enable recovery in case of data corruption or deletion.
