CVE-2025-7663 is a vulnerability classified under CWE-862 (Missing Authorization) found in the Ovatheme Events Manager plugin for WordPress, specifically in all versions up to and including 1.8.6. The root cause is the absence of proper capability checks in several functions within the /class-ovaem-ajax.php file. This missing authorization allows unauthenticated attackers to invoke sensitive actions such as deleting ticket files and downloading tickets without any authentication or user interaction. The vulnerability is remotely exploitable over the network (AV:N), requires low attack complexity (AC:L), and no privileges (PR:N) or user interaction (UI:N). The scope is unchanged (S:U), meaning the exploit affects only the vulnerable component without impacting other system components. The confidentiality and integrity of ticket files are at risk, as attackers can access and delete these files, potentially leading to data leakage and disruption of event ticketing operations. However, availability is not impacted. No patches or fixes are currently linked, and no known exploits have been reported in the wild as of the publication date. The vulnerability was reserved in July 2025 and published in November 2025, with a CVSS v3.1 base score of 6.5, indicating medium severity. The plugin is widely used in WordPress sites for event management, making this vulnerability relevant to many organizations relying on this plugin for ticket handling and event coordination.

The vulnerability allows unauthenticated attackers to access and delete ticket files managed by the Ovatheme Events Manager plugin, compromising the confidentiality and integrity of sensitive ticket data. This can lead to unauthorized disclosure of ticket information, potentially exposing customer data or event details. Deletion of ticket files can disrupt event operations, causing administrative overhead and loss of trust from customers. Although availability of the overall system is not directly impacted, the loss or theft of ticket data can have significant operational and reputational consequences for organizations relying on this plugin. Attackers could exploit this vulnerability to manipulate event attendance or cause confusion by deleting tickets. The ease of exploitation without authentication increases the risk of widespread attacks, especially on publicly accessible WordPress sites. Organizations using this plugin in sectors such as entertainment, conferences, and ticketed events are particularly vulnerable to operational disruption and data leakage.

To mitigate this vulnerability, organizations should immediately update the Ovatheme Events Manager plugin to a patched version once released by the vendor. In the absence of an official patch, administrators should implement strict access controls on the /class-ovaem-ajax.php endpoint, such as restricting access by IP address or requiring authentication at the web server or application firewall level. Employing a Web Application Firewall (WAF) with custom rules to block unauthorized AJAX requests targeting this plugin can reduce exposure. Regularly audit plugin permissions and capabilities to ensure that sensitive functions require appropriate authorization. Monitoring web server logs for suspicious access patterns to the plugin’s AJAX endpoints can help detect exploitation attempts. Additionally, consider isolating or disabling the plugin if it is not critical to operations until a fix is available. Backup ticket data frequently to enable recovery in case of deletion or tampering. Finally, maintain an up-to-date inventory of WordPress plugins and their versions to quickly identify vulnerable instances.
