CVE-2025-64257 identifies a missing authorization vulnerability in the Joe Dolson My Tickets plugin, specifically affecting versions up to and including 2.1.0. The vulnerability stems from incorrectly configured access control security levels within the plugin, which is used for managing ticket sales and event registrations on websites, typically WordPress-based. Missing authorization means that certain functions or data that should be restricted to authorized users are accessible without proper permission checks. This can allow an attacker to bypass security controls and access or manipulate ticketing information, potentially including sensitive user data or administrative functions. Although no exploits have been reported in the wild, the vulnerability is significant because it compromises the fundamental security principle of access control. The lack of a CVSS score suggests the vulnerability is newly published and not yet fully assessed, but the nature of missing authorization typically implies a high risk. The vulnerability does not require user interaction, and exploitation can be performed remotely if the plugin is accessible. The affected versions are not precisely enumerated beyond being less than or equal to 2.1.0, and no patch links are currently available, indicating that users must monitor vendor updates closely. The vulnerability was reserved and published in late 2025, highlighting the need for immediate attention by administrators using this plugin. Since the plugin is used in event ticketing, unauthorized access could lead to data breaches, fraudulent ticket issuance, or disruption of event management services.

For European organizations, the impact of CVE-2025-64257 can be significant, especially for those relying on the Joe Dolson My Tickets plugin for event management and ticket sales. Unauthorized access could lead to exposure of personal data of attendees, including names, contact information, and payment details, violating GDPR and other data protection regulations. Integrity of ticketing data could be compromised, allowing attackers to manipulate ticket availability or create fraudulent tickets, causing financial losses and reputational damage. Availability might also be affected if attackers disrupt ticketing operations or cause denial of service through unauthorized actions. Organizations in sectors such as entertainment, conferences, and public events are particularly vulnerable. The breach of confidentiality and integrity can result in regulatory penalties, loss of customer trust, and operational disruptions. Given the plugin’s integration with WordPress, a widely used CMS in Europe, the scope of affected systems could be broad. The absence of known exploits provides a window for proactive mitigation, but the risk remains high due to the ease of exploitation and lack of authentication barriers.

1. Immediately audit all installations of the Joe Dolson My Tickets plugin to identify affected versions (<= 2.1.0). 2. Monitor the vendor’s official channels for patch releases and apply updates as soon as they become available. 3. In the interim, restrict access to the plugin’s administrative and ticket management interfaces using web application firewalls (WAFs) or IP whitelisting to limit exposure. 4. Review and harden access control configurations within the plugin settings and the hosting environment to ensure least privilege principles are enforced. 5. Implement comprehensive logging and monitoring to detect unusual access patterns or unauthorized attempts to interact with the ticketing system. 6. Conduct penetration testing focused on access control mechanisms to identify any other potential weaknesses. 7. Educate event management and IT staff about the risks and signs of exploitation related to this vulnerability. 8. Consider temporary disabling the plugin if critical events are upcoming and no patch is available, replacing it with alternative ticketing solutions. 9. Ensure backups of ticketing data are regularly performed and securely stored to enable recovery in case of compromise. 10. Coordinate with legal and compliance teams to prepare for potential incident response and notification obligations under GDPR.
