CVE-2025-64257 is a missing authorization vulnerability identified in the Joe Dolson My Tickets plugin, specifically affecting versions up to and including 2.1.0. This vulnerability arises from incorrectly configured access control security levels, allowing an attacker with low privileges (PR:L) to perform unauthorized actions that impact the integrity of the system. The vulnerability is exploitable remotely (AV:N) without requiring user interaction (UI:N), and it does not escalate privileges or affect confidentiality or availability. The core issue is that the plugin fails to properly verify whether a user is authorized to perform certain operations, enabling unauthorized modification of ticket data or related information. While no known exploits are currently reported in the wild, the vulnerability presents a risk for systems relying on this plugin for event or ticket management. The absence of patches at the time of reporting necessitates immediate attention to access control configurations. The CVSS v3.1 base score of 4.3 reflects a medium severity level, primarily due to the limited impact scope and the requirement for some privileges to exploit the flaw.

For European organizations, the primary impact of this vulnerability is the potential unauthorized modification of ticketing or event-related data, which could lead to data integrity issues such as fraudulent ticket issuance, manipulation of event attendance records, or disruption of event management workflows. Although confidentiality and availability are not directly affected, the integrity compromise could undermine trust in event systems and lead to financial or reputational damage. Organizations using the affected plugin in sectors such as entertainment, conferences, or public events may face operational disruptions or customer dissatisfaction. Given the remote exploitability and lack of user interaction required, attackers could automate exploitation attempts, increasing risk. The medium severity indicates that while the threat is not critical, it should be addressed promptly to prevent escalation or combined attacks.

European organizations should immediately audit their use of the Joe Dolson My Tickets plugin and verify if they are running versions up to 2.1.0. Until an official patch is released, administrators should restrict access to the plugin’s management interfaces to trusted users only, implementing strict role-based access controls. Reviewing and tightening access control policies within the plugin configuration is essential to prevent unauthorized actions. Network-level controls such as web application firewalls (WAFs) can be configured to monitor and block suspicious requests targeting the plugin endpoints. Organizations should subscribe to vendor notifications for patch releases and apply updates promptly once available. Additionally, monitoring logs for unusual activity related to ticket management functions can help detect exploitation attempts early. For long-term mitigation, consider alternative ticketing solutions with robust access control mechanisms if patching is delayed.
