CVE-2025-62869 identifies a missing authorization vulnerability in the Gravitec.net Web Push Notifications plugin, specifically affecting versions up to and including 2.9.17. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user permissions. This misconfiguration can allow attackers to perform unauthorized actions within the system, such as modifying push notification settings or accessing sensitive data related to notifications. The vulnerability does not require prior authentication or user interaction, increasing its risk profile. Although no public exploits have been reported, the flaw's presence in a widely used push notification service poses a significant threat. The absence of a CVSS score indicates the need for a severity assessment based on impact and exploitability factors. The vulnerability primarily impacts the confidentiality and integrity of notification data and could disrupt the availability of notification services if exploited. The technical details confirm the issue was reserved in late October 2025 and published in December 2025, with no patches currently available, emphasizing the need for proactive mitigation.

For European organizations, exploitation of this vulnerability could lead to unauthorized access to web push notification configurations, potentially allowing attackers to send fraudulent notifications, manipulate marketing campaigns, or access sensitive user engagement data. This could damage brand reputation, lead to misinformation, and violate data protection regulations such as GDPR if personal data is exposed or misused. The integrity of communication channels would be compromised, undermining user trust. Additionally, unauthorized changes could disrupt notification delivery, impacting customer engagement and operational workflows. Organizations relying heavily on digital marketing and customer outreach via push notifications are particularly at risk. The lack of authentication requirements and ease of exploitation increase the threat level, making it critical for affected entities to address the vulnerability promptly.

European organizations should immediately audit their Gravitec.net Web Push Notifications configurations to identify and correct any improperly set access controls. Implement strict role-based access control (RBAC) policies to ensure only authorized personnel can modify notification settings. Monitor logs for unusual activity related to push notification management, such as unexpected configuration changes or unauthorized access attempts. Engage with Gravitec.net support to obtain information on upcoming patches or security updates and apply them promptly once available. Consider temporarily disabling the plugin or limiting its use until a fix is deployed if the risk is deemed high. Educate staff on the risks associated with push notification management and enforce strong authentication mechanisms for administrative access. Additionally, review and enhance overall web application security posture to prevent lateral movement if exploitation occurs.
