CVE-2026-2217 is a SQL injection vulnerability identified in the itsourcecode Event Management System version 1.0, specifically within an unspecified function in the /admin/manage_user.php file. The vulnerability arises from improper sanitization or validation of the 'ID' parameter, which is susceptible to malicious SQL payloads. This allows remote attackers to inject and execute arbitrary SQL commands on the backend database without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/AT:N/UI:N/PR:N). The impact includes unauthorized data access, modification, or deletion, potentially compromising the confidentiality, integrity, and availability of the system's data. The vulnerability has a CVSS 4.0 base score of 6.9, categorized as medium severity, reflecting the ease of exploitation and the potential impact. Although no active exploits have been reported in the wild, the public disclosure of exploit code increases the likelihood of attacks. The lack of patches or vendor advisories necessitates immediate mitigation efforts by affected organizations. The vulnerability affects only version 1.0 of the product, suggesting that upgrading or patching could resolve the issue. The attack vector is network-based, targeting the administrative interface, which may be exposed in some deployments. This vulnerability is critical for organizations relying on this event management system to safeguard sensitive user and event data from unauthorized access or manipulation.

For European organizations using itsourcecode Event Management System 1.0, this vulnerability poses a significant risk of unauthorized database access and manipulation. Exploitation could lead to data breaches involving personal or event-related information, undermining data privacy compliance obligations such as GDPR. Integrity of event management data could be compromised, affecting operational reliability and trustworthiness of event records. Availability may also be impacted if attackers execute destructive SQL commands, potentially disrupting event management services. Given the remote, unauthenticated nature of the exploit, attackers can operate from anywhere, increasing the threat surface. Organizations managing large-scale or sensitive events in Europe could face reputational damage, regulatory penalties, and operational disruptions if exploited. The medium severity score suggests moderate but non-negligible risk, warranting prompt attention especially in sectors with strict data protection requirements or critical event infrastructure.

1. Immediately restrict access to the /admin/manage_user.php interface through network-level controls such as VPNs, IP whitelisting, or firewall rules to limit exposure. 2. Conduct a thorough code review of the affected parameter 'ID' and refactor the code to use parameterized queries or prepared statements to prevent SQL injection. 3. If available, apply official patches or updates from the vendor; if not, consider upgrading to a newer, unaffected version of the software. 4. Implement Web Application Firewalls (WAF) with SQL injection detection and prevention rules tailored to the application’s traffic patterns. 5. Monitor logs for suspicious database queries or unusual access patterns targeting the admin interface. 6. Educate administrators on the risks and ensure strong authentication and session management for admin access. 7. Regularly back up event management data and verify backup integrity to enable recovery in case of data corruption or deletion. 8. Engage in threat hunting and vulnerability scanning to detect any attempts to exploit this vulnerability within the network environment.
