CVE-2025-62072 is a missing authorization vulnerability identified in the Rustaurius Front End Users product, affecting versions up to and including 3.2.33. This vulnerability arises because the application fails to properly enforce authorization checks on certain front-end user operations, allowing users with low privileges (PR:L) to access resources or functionalities that should be restricted. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) indicates that the vulnerability can be exploited remotely over the network with low attack complexity, requiring only low privileges and no user interaction. The impact is limited to confidentiality, meaning some sensitive information could be disclosed, but the integrity and availability of the system remain unaffected. No known exploits have been reported in the wild, suggesting that active exploitation is not currently observed. The vulnerability affects front-end-only user components, which are typically part of web applications that manage user interactions on the client side. Because the flaw is in authorization logic, it could allow unauthorized data access or information leakage within the scope of front-end user operations. The lack of vendor patch links indicates that a fix may not yet be publicly available, so organizations must rely on compensating controls until a patch is released.

For European organizations, the primary impact of CVE-2025-62072 is the potential unauthorized disclosure of sensitive front-end user data, which could include personal information or business-sensitive details depending on the application context. This could lead to privacy violations under GDPR and damage organizational reputation. Since the vulnerability does not affect integrity or availability, it is less likely to cause service disruption or data manipulation. However, unauthorized data exposure can still facilitate further attacks such as social engineering or targeted phishing. Organizations with web applications using Rustaurius Front End Users are at risk, especially those in sectors handling sensitive user data like finance, healthcare, or government services. The medium severity rating suggests that while the threat is not critical, it warrants timely attention to avoid escalation or exploitation by attackers. The absence of known exploits reduces immediate risk but does not eliminate the need for vigilance.

1. Conduct a thorough audit of access control and authorization logic within Rustaurius Front End Users implementations to identify and restrict unauthorized access paths. 2. Implement strict role-based access controls (RBAC) and ensure that front-end user operations enforce these controls consistently. 3. Monitor application logs and user activity for unusual access patterns or attempts to access restricted functionalities. 4. Apply network segmentation and firewall rules to limit exposure of the affected front-end services to trusted users and networks only. 5. Engage with the Rustaurius vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. 6. Until patches are applied, consider deploying web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting authorization weaknesses. 7. Educate development and security teams about the importance of authorization checks in front-end components to prevent similar issues in future releases.
