CVE-2025-68015 is a critical vulnerability classified as improper control of generation of code, commonly known as code injection, affecting the Vollstart Event Tickets with Ticket Scanner plugin up to version 2.8.3. This vulnerability allows an unauthenticated attacker to remotely inject malicious code into the system, which can then be executed with the privileges of the application. The vulnerability arises due to insufficient validation or sanitization of input data that is used to generate code dynamically within the plugin. The CVSS v3.1 base score is 9.0, with an attack vector of network (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), and a scope change (S:C), indicating that the vulnerability affects resources beyond the initially vulnerable component. The impact metrics indicate high confidentiality (C:H), integrity (I:H), and availability (A:H) impacts, meaning successful exploitation can lead to complete system compromise, data theft, or service disruption. Although no public exploits are currently known, the critical nature of the flaw and the widespread use of the plugin in event management systems make it a significant threat. The vulnerability was reserved in December 2025 and published in January 2026, suggesting recent discovery and disclosure. The lack of available patches at the time of reporting necessitates immediate attention from users of the affected software. The plugin is commonly used in event ticketing systems, which are often integrated with web platforms, increasing the attack surface. The vulnerability's exploitation could allow attackers to execute arbitrary commands, deploy malware, or pivot within the network, potentially impacting broader organizational infrastructure.

For European organizations, the impact of CVE-2025-68015 is substantial due to the critical nature of the vulnerability and the potential for full system compromise. Organizations relying on the Vollstart Event Tickets with Ticket Scanner plugin for managing event registrations and ticketing face risks including unauthorized access to sensitive customer data, manipulation or cancellation of event tickets, disruption of event operations, and potential ransomware or malware deployment. The confidentiality breach could expose personal data of attendees, violating GDPR and other data protection regulations, leading to legal and financial penalties. Integrity and availability impacts could disrupt event services, causing reputational damage and financial losses, especially for large-scale events or recurring conferences. The high attack complexity somewhat limits exploitation but does not eliminate risk, particularly if attackers can leverage other vulnerabilities or social engineering. The lack of authentication and user interaction requirements means attacks can be automated and launched remotely, increasing the threat to organizations with internet-facing ticketing systems. Additionally, the scope change indicates that exploitation could affect other components beyond the plugin itself, potentially compromising the hosting web server or connected systems.

1. Immediate monitoring for any unusual activity or signs of exploitation related to the Event Tickets with Ticket Scanner plugin is essential. 2. Apply patches or updates from Vollstart as soon as they become available; if no official patch exists, consider temporary removal or disabling of the plugin until a fix is released. 3. Implement strict input validation and sanitization on all user inputs related to ticket scanning and event registration to prevent injection of malicious code. 4. Employ web application firewalls (WAFs) configured to detect and block code injection attempts targeting the plugin. 5. Conduct thorough vulnerability scanning and penetration testing focusing on the ticketing system and associated web services. 6. Restrict network exposure of the ticketing system to only necessary users and services, using segmentation and access controls. 7. Maintain regular backups of event data and system configurations to enable recovery in case of compromise. 8. Educate IT and security teams about this vulnerability and ensure incident response plans include scenarios involving code injection attacks on event management platforms. 9. Review and harden server and application configurations to minimize the impact of potential exploitation, including least privilege principles and disabling unnecessary features.
