CVE-2025-7663 is a vulnerability classified under CWE-862 (Missing Authorization) found in the Ovatheme Events Manager plugin for WordPress, affecting all versions up to and including 1.8.6. The vulnerability is due to the absence of proper capability checks in several functions within the /class-ovaem-ajax.php file. This lack of authorization verification allows unauthenticated attackers to invoke AJAX actions that should be restricted, such as deleting ticket files and downloading tickets, without any authentication or user interaction. The vulnerability has a CVSS 3.1 base score of 6.5, indicating medium severity, with an attack vector of network (remote), low attack complexity, no privileges required, and no user interaction needed. The impact primarily affects confidentiality and integrity, as attackers can access and delete sensitive ticket data, but availability is not impacted. No official patches or fixes have been released at the time of publication, and no known exploits have been observed in the wild. The vulnerability poses a risk to WordPress sites using this plugin, especially those handling event ticketing, where ticket data confidentiality and integrity are critical. The missing authorization checks represent a fundamental security flaw that could be exploited by attackers to compromise sensitive event-related data.

For European organizations, the vulnerability can lead to unauthorized disclosure and deletion of ticket files, potentially exposing personal data of event attendees and disrupting event management processes. This could result in reputational damage, loss of customer trust, and potential regulatory penalties under GDPR due to unauthorized access to personal data. Organizations relying on Ovatheme Events Manager for ticket sales and event coordination may face operational challenges if ticket data is manipulated or deleted. While availability is not directly impacted, the integrity and confidentiality breaches could indirectly affect business continuity and customer relations. The risk is heightened for organizations with high volumes of ticket transactions or sensitive attendee information. Additionally, the lack of authentication requirement means attackers can exploit the vulnerability remotely without needing credentials, increasing the attack surface. European entities involved in cultural, entertainment, or conference sectors using WordPress with this plugin are particularly vulnerable.

Immediate mitigation should focus on restricting access to the vulnerable AJAX endpoints by implementing web application firewall (WAF) rules that block unauthenticated requests to /class-ovaem-ajax.php functions. Administrators should audit and monitor server logs for unusual access patterns or unauthorized ticket file downloads and deletions. Until an official patch is released, consider disabling or uninstalling the Ovatheme Events Manager plugin if feasible, or replacing it with a more secure event management solution. Applying the principle of least privilege on WordPress user roles and capabilities can reduce risk, though it does not fully mitigate this unauthenticated flaw. Organizations should also ensure that backups of ticket data are regularly performed and securely stored to enable recovery from potential data loss. Once a patch becomes available, prompt application is critical. Additionally, educating site administrators about this vulnerability and encouraging vigilance against suspicious activity will help reduce exploitation risk.
