CVE-2025-62972 is a vulnerability identified in the WPWebinarSystem WebinarPress WordPress plugin, specifically in versions up to and including 1.33.28. The issue arises from missing authorization checks, meaning that certain actions within the plugin can be performed by users who do not have the appropriate permissions. This misconfiguration of access control security levels allows users with limited privileges (low-level authenticated users) to access or manipulate webinar-related functionalities or data that should be restricted. The vulnerability is remotely exploitable over the network without requiring user interaction, which increases its risk profile. However, the CVSS score of 4.3 (medium severity) reflects that the impact is limited to confidentiality with no direct impact on integrity or availability. The vulnerability does not require elevated privileges beyond a low-level authenticated user, and no known exploits have been reported in the wild as of the publication date. The lack of patch links suggests that a fix may not yet be publicly available, emphasizing the need for vigilance and interim mitigations. WebinarPress is a popular plugin used to manage and host webinars on WordPress sites, so this vulnerability could expose sensitive webinar content or user data if exploited. The root cause is an incorrectly configured access control mechanism within the plugin's code, which fails to verify user permissions properly before allowing certain operations.

For European organizations, the impact of CVE-2025-62972 primarily concerns the confidentiality of webinar-related information. Unauthorized users with low-level access could potentially view or extract sensitive data such as webinar schedules, participant lists, or content that should be restricted. While the vulnerability does not affect data integrity or system availability, the exposure of confidential information could lead to reputational damage, loss of trust, or compliance issues under regulations like GDPR. Organizations that rely heavily on WebinarPress for internal or external communications, training, or marketing webinars are at higher risk. The medium severity rating indicates that while the threat is not critical, it should not be ignored, especially in sectors handling sensitive or regulated data. The absence of known exploits reduces immediate risk but does not eliminate the potential for future attacks. European entities with public-facing WordPress sites using this plugin should consider the threat significant enough to warrant prompt action.

1. Immediately audit user roles and permissions within WordPress to ensure that only trusted users have access to webinar management features. 2. Restrict access to the WebinarPress plugin functionalities to the minimum necessary user roles, ideally limiting to administrators or trusted editors. 3. Monitor WordPress logs and webinar-related activity for unusual access patterns or unauthorized attempts. 4. Apply any official patches or updates from WPWebinarSystem as soon as they become available; subscribe to vendor security advisories. 5. If no patch is available, consider temporarily disabling the WebinarPress plugin or replacing it with alternative webinar solutions until the vulnerability is resolved. 6. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting WebinarPress endpoints. 7. Educate internal users about the risks of privilege escalation and enforce strong authentication policies. 8. Regularly back up WordPress sites and webinar data to enable recovery in case of compromise.
