The vulnerability identified as CVE-2026-2689 affects the itsourcecode Event Management System version 1.0. It is a SQL Injection flaw located in the /admin/manage_booking.php file, where the ID parameter is improperly sanitized, allowing attackers to inject malicious SQL commands. This injection can be performed remotely without authentication or user interaction, making it a critical entry point for attackers to manipulate backend databases. The vulnerability can lead to unauthorized data disclosure, modification, or deletion, compromising the confidentiality, integrity, and availability of the system's data. The CVSS 4.0 base score is 6.9, reflecting a medium severity level due to the lack of privilege and user interaction requirements but limited scope and impact. Although no active exploits have been reported in the wild, the public availability of exploit code increases the risk of exploitation. The affected product is primarily used for event management, which often involves sensitive booking and user data. The lack of official patches at the time of publication necessitates immediate mitigation efforts by organizations. The vulnerability highlights the importance of secure coding practices, especially input validation and parameterized queries, to prevent SQL injection attacks.

For European organizations, exploitation of this vulnerability could result in unauthorized access to sensitive booking and user information, leading to data breaches and privacy violations under GDPR. The integrity of event management data could be compromised, causing incorrect bookings, cancellations, or financial discrepancies. Availability of the event management system may also be affected if attackers execute destructive SQL commands, disrupting business operations and event planning activities. Organizations handling large volumes of personal or payment data are at higher risk of reputational damage and regulatory penalties. The remote and unauthenticated nature of the exploit increases the attack surface, especially for organizations exposing the administrative interface to the internet. This vulnerability could also be leveraged as a foothold for further network intrusion or lateral movement within the organization’s infrastructure.

1. Immediately restrict access to the /admin/manage_booking.php interface by implementing IP whitelisting or VPN-only access to reduce exposure. 2. Employ web application firewalls (WAFs) with SQL injection detection and blocking capabilities to intercept malicious payloads targeting the ID parameter. 3. Conduct thorough input validation and sanitize all user-supplied inputs, especially the ID parameter, using parameterized queries or prepared statements to prevent injection. 4. Monitor logs for unusual database query patterns or repeated access attempts to the vulnerable endpoint. 5. Engage with the vendor or community to obtain or develop patches and apply them promptly once available. 6. Perform regular security assessments and code reviews of the event management system to identify and remediate similar vulnerabilities. 7. Educate administrators and developers about secure coding practices and the risks of SQL injection. 8. Consider isolating the event management system within a segmented network zone to limit potential lateral movement if compromised.
