CVE-2025-53293 is a medium-severity vulnerability classified under CWE-862 (Missing Authorization) affecting the Dashboard Widget Sidebar developed by Morten Dalgaard Johansen, specifically versions up to 1.2.3. The vulnerability arises due to incorrectly configured access control security levels, allowing an attacker with limited privileges (PR:L - privileges required: low) to perform unauthorized actions that impact the integrity of the system. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N) indicates that the attack can be executed remotely over the network without user interaction, requires low privileges, and affects the integrity of the system without impacting confidentiality or availability. Essentially, the missing authorization check means that certain operations or modifications within the Dashboard Widget Sidebar can be performed by users who should not have permission, potentially allowing unauthorized changes to the widget's configuration or behavior. Although no known exploits are currently reported in the wild and no patches have been linked yet, the vulnerability represents a risk especially in environments where multiple users have access to the dashboard interface, such as multi-tenant or collaborative platforms. The lack of authorization checks can be exploited to alter dashboard widgets, potentially leading to misleading information display or manipulation of dashboard data, which can affect decision-making processes or system monitoring.

For European organizations, the impact of this vulnerability can be significant depending on the role of the Dashboard Widget Sidebar within their IT infrastructure. Organizations relying on this widget for critical monitoring, reporting, or operational dashboards may face integrity issues where unauthorized users could alter displayed information or configurations, leading to incorrect business decisions or security oversight. While confidentiality and availability are not directly affected, the integrity compromise can undermine trust in the dashboard data. This is particularly relevant for sectors such as finance, healthcare, manufacturing, and public administration where dashboards are used for real-time monitoring and compliance reporting. Additionally, if the widget is integrated into larger enterprise platforms or used in multi-user environments, the risk of insider threats or lateral movement by low-privileged users increases. The medium CVSS score suggests that while the vulnerability is not trivial, it requires some level of access, which may limit exposure but still poses a risk in environments with many users or weak internal access controls.

To mitigate CVE-2025-53293 effectively, European organizations should: 1) Immediately review and audit access control configurations for the Dashboard Widget Sidebar to ensure that authorization checks are properly enforced for all sensitive operations. 2) Implement role-based access control (RBAC) or attribute-based access control (ABAC) mechanisms to restrict widget configuration and modification capabilities strictly to authorized personnel. 3) Monitor and log all changes to dashboard widgets to detect unauthorized modifications promptly. 4) If possible, isolate the widget environment or restrict network access to trusted users only, reducing the attack surface. 5) Engage with the vendor or developer (Morten Dalgaard Johansen) to obtain patches or updates as soon as they become available and apply them promptly. 6) Conduct internal penetration testing focusing on access control weaknesses in dashboard components to proactively identify and remediate similar issues. 7) Educate users with dashboard access about the risks of unauthorized changes and enforce strong authentication and session management to prevent privilege escalation.
