The vulnerability identified as CVE-2025-7663 affects the Ovatheme Events Manager plugin for WordPress, specifically all versions up to and including 1.8.6. The root cause is a missing authorization (capability) check in several functions within the /class-ovaem-ajax.php file. This omission allows unauthenticated attackers to invoke AJAX functions that should be restricted, enabling them to delete ticket files, download tickets, and potentially perform other unauthorized actions related to event ticket management. The vulnerability is classified under CWE-862 (Missing Authorization), indicating that the plugin fails to verify whether the requester has the necessary permissions before executing sensitive operations. The CVSS v3.1 base score is 6.5 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), and low impact on confidentiality and integrity (C:L/I:L), with no impact on availability (A:N). No patches or fixes were linked at the time of reporting, and no exploits have been observed in the wild. The vulnerability could lead to unauthorized access and manipulation of ticket data, potentially exposing sensitive customer information or disrupting event operations if ticket files are deleted.

For European organizations, the impact of CVE-2025-7663 can be significant, especially for those relying on the Ovatheme Events Manager plugin to handle event ticketing and related data. Unauthorized deletion of ticket files could disrupt event management workflows, causing operational challenges and potential financial losses. Unauthorized downloading of tickets or ticket data could lead to confidentiality breaches, exposing customer information or enabling fraudulent ticket use. While availability is not directly impacted, the integrity and confidentiality concerns could damage organizational reputation and customer trust. Given the plugin’s integration with WordPress, a widely used CMS in Europe, the attack surface is considerable. Organizations in sectors such as entertainment, conferences, and ticketed events are particularly vulnerable. The lack of authentication requirements and user interaction makes exploitation easier, increasing the risk of automated or opportunistic attacks. Additionally, GDPR compliance considerations mean that unauthorized data exposure could result in regulatory penalties.

1. Monitor for and apply any official patches or updates from Ovatheme immediately once released to address the missing authorization checks. 2. In the absence of patches, restrict access to the /class-ovaem-ajax.php endpoint by implementing web application firewall (WAF) rules or server-level access controls to allow only trusted IP addresses or authenticated users. 3. Disable or remove the Ovatheme Events Manager plugin if it is not essential to reduce the attack surface. 4. Implement strict WordPress user role and capability management to minimize permissions for users interacting with event management functions. 5. Conduct regular security audits and log monitoring to detect unusual access patterns or unauthorized attempts to invoke AJAX functions related to the plugin. 6. Educate site administrators on the risks of using outdated plugins and the importance of timely updates. 7. Consider isolating event management functionalities on separate subdomains or environments with additional security controls. 8. Backup ticket data regularly to enable recovery in case of deletion or tampering.
