CVE-2025-62972 is a vulnerability identified in the WPWebinarSystem WebinarPress WordPress plugin, specifically affecting versions up to and including 1.33.28. The core issue is a missing authorization check, meaning that certain functions or data within the plugin can be accessed by users who do not have the appropriate permissions. This is a classic access control flaw where the plugin fails to enforce security levels correctly, allowing privilege escalation or unauthorized data access. The vulnerability is remotely exploitable over the network without requiring user interaction, and the attack complexity is low, meaning an attacker with some level of authenticated access (low privileges) can exploit it. The CVSS score of 4.3 reflects a medium severity, primarily due to limited confidentiality impact and no impact on integrity or availability. The vulnerability could allow an attacker to view sensitive webinar-related information or perform actions reserved for higher privileged users, potentially leading to information disclosure. However, no known exploits have been reported in the wild, and no official patches have been released at the time of this report. The vulnerability was reserved and published in late October 2025 by Patchstack. Organizations using WebinarPress should be aware of this risk, especially if they rely on the plugin for critical webinar hosting and management functions.

For European organizations, the missing authorization vulnerability in WebinarPress could lead to unauthorized access to sensitive webinar content, participant data, or administrative functions. This exposure can undermine confidentiality, potentially leaking private business communications, customer information, or intellectual property shared during webinars. Although the vulnerability does not affect data integrity or availability, unauthorized access could facilitate further attacks or social engineering by exposing internal processes or user details. Organizations in sectors such as education, professional training, marketing, and event management that heavily rely on webinars for communication and business operations are particularly at risk. The impact is heightened in regulated industries where data privacy laws like GDPR impose strict controls on personal data handling. Failure to secure webinar platforms could result in compliance violations and reputational damage. Since exploitation requires some level of authenticated access, insider threats or compromised low-privilege accounts pose a significant risk vector.

To mitigate this vulnerability, European organizations should first audit user roles and permissions within the WebinarPress plugin, ensuring that only trusted users have access to sensitive functions. Implement the principle of least privilege by restricting access rights to the minimum necessary. Monitor and analyze access logs for unusual or unauthorized activity related to webinar management. Until an official patch is released, consider disabling or limiting the use of affected WebinarPress features that require elevated privileges. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin endpoints. Regularly update WordPress core and all plugins to the latest versions once patches become available. Additionally, conduct user awareness training to reduce the risk of credential compromise that could facilitate exploitation. For critical webinar content, consider alternative secure platforms or additional encryption layers to protect data confidentiality.
