CVE-2025-62027 is a Missing Authorization vulnerability identified in the StellarWP Event Tickets plugin, affecting all versions up to and including 5.26.3. This vulnerability arises because the plugin fails to properly verify whether a user has the necessary permissions before allowing access to certain functionalities or data. Specifically, an attacker with low privileges (PR:L) can remotely (AV:N) exploit this flaw without requiring user interaction (UI:N), potentially accessing or modifying data they should not be authorized to handle. The vulnerability impacts the confidentiality and integrity of the system, as unauthorized users might view or alter event ticket information or related data. However, it does not affect system availability. The vulnerability has a CVSS v3.1 base score of 5.4, indicating a medium severity level. No public exploits have been reported yet, but the lack of authorization checks makes it a significant concern for organizations relying on this plugin for event management. The issue was published on October 22, 2025, and was reserved earlier that month. The absence of patch links suggests that a fix may still be pending or in development, underscoring the importance of monitoring vendor updates.

For European organizations, this vulnerability could lead to unauthorized access to sensitive event-related data, including attendee information, ticket details, and potentially financial transaction data if integrated with payment systems. This could result in data breaches compromising personal data protected under GDPR, leading to regulatory penalties and reputational damage. Unauthorized modifications could disrupt event operations, causing logistical issues and loss of trust among customers and partners. Since the plugin is widely used in WordPress-based event management, organizations relying on it for ticket sales and event coordination are at risk. The medium severity indicates moderate risk, but the ease of exploitation and lack of user interaction required increase the urgency for mitigation. The impact is particularly relevant for sectors with frequent public events, such as entertainment, conferences, and cultural institutions across Europe.

1. Monitor StellarWP communications and security advisories closely for the release of a patch addressing CVE-2025-62027 and apply updates immediately upon availability. 2. Until a patch is released, restrict access to the Event Tickets plugin functionalities by limiting user roles and permissions to only trusted administrators and event managers. 3. Implement web application firewalls (WAF) with custom rules to detect and block suspicious requests targeting Event Tickets endpoints. 4. Conduct regular audits of user permissions within WordPress to ensure no excessive privileges are granted that could be exploited. 5. Employ logging and monitoring to detect unusual access patterns or unauthorized changes related to event ticket data. 6. Consider temporarily disabling the Event Tickets plugin if it is not critical to operations or if the risk outweighs the benefits until a fix is applied. 7. Educate staff managing the plugin about the vulnerability and encourage vigilance for any anomalies in event ticketing processes.
