CVE-2025-62972 identifies a missing authorization vulnerability in the WPWebinarSystem WebinarPress WordPress plugin, specifically versions up to 1.33.28. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user permissions within the plugin. This misconfiguration can allow an attacker to perform unauthorized actions, such as accessing or modifying webinar data, without proper authentication or authorization checks. The vulnerability is classified as an access control flaw, which is critical in web applications managing sensitive data or user interactions. Although no exploits have been reported in the wild, the nature of the vulnerability suggests that exploitation could be straightforward, especially if the plugin is publicly accessible on a WordPress site. The plugin is commonly used to manage and host webinars, meaning that exploitation could compromise the confidentiality of webinar content, integrity of user data, and potentially disrupt webinar availability. The absence of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the technical details and impact suggest a significant risk. The vulnerability affects all versions up to 1.33.28, with no specific earliest affected version identified. The issue was reserved and published in late October 2025 by Patchstack, a known security entity focusing on WordPress vulnerabilities. Given the widespread use of WordPress and the increasing reliance on webinar platforms, this vulnerability poses a notable threat to organizations relying on WebinarPress for their digital events.

For European organizations, the impact of CVE-2025-62972 can be substantial. Unauthorized access to webinar management functions could lead to exposure of sensitive corporate communications, intellectual property, or personal data of attendees. Integrity of webinar content could be compromised, allowing attackers to alter or disrupt scheduled events, damaging organizational reputation and trust. Availability of webinar services might be affected if attackers manipulate or disable webinar sessions. Organizations in sectors such as education, finance, healthcare, and government that use WebinarPress for secure communications are particularly vulnerable. The breach of confidentiality and integrity could also lead to regulatory non-compliance under GDPR, resulting in legal and financial penalties. Moreover, the ease of exploitation without authentication increases the risk of automated attacks targeting vulnerable WebinarPress installations across Europe. This could lead to widespread disruption in digital event hosting and communication channels critical for business continuity.

1. Immediately monitor the WPWebinarSystem vendor’s official channels for patches addressing CVE-2025-62972 and apply them as soon as they become available. 2. In the interim, restrict access to the WebinarPress plugin’s administrative and management interfaces using network-level controls such as IP whitelisting or VPN access to reduce exposure. 3. Conduct a thorough audit of user roles and permissions within WordPress to ensure that only trusted users have access to webinar management functions. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting WebinarPress endpoints, focusing on unauthorized access attempts. 5. Enable detailed logging and monitoring of plugin-related activities to quickly identify potential exploitation attempts. 6. Educate administrators and users about the risk and encourage prompt reporting of unusual webinar behavior or access anomalies. 7. Consider temporary disabling of the WebinarPress plugin if the risk outweighs operational needs until a patch is applied. 8. Review and enhance overall WordPress security posture, including timely updates of all plugins and core software, to reduce attack surface.
