CVE-2025-46296 is an authorization bypass vulnerability discovered in the Claris FileMaker Server Admin Console. The flaw allows users assigned administrator roles with minimal privileges to bypass intended access restrictions and gain unauthorized access to sensitive administrative features. Specifically, these users can view license details and download application logs, which are typically restricted to higher-privileged administrators. This vulnerability arises from insufficient enforcement of privilege checks within the Admin Console interface, enabling privilege escalation within the administrative environment. The affected versions are unspecified, but the issue has been fully remediated in FileMaker Server version 22.0.4. The vulnerability does not require user interaction but does require an authenticated session with an administrator role, albeit with minimal privileges. No public exploits or active exploitation campaigns have been reported to date. The exposure of license details and application logs could reveal sensitive operational information, potentially aiding further attacks or unauthorized access. The vulnerability highlights the importance of strict role-based access control enforcement in administrative interfaces of server software. Organizations using FileMaker Server should prioritize patching to the fixed version and audit their administrator role assignments to ensure least privilege principles are enforced.

For European organizations, this vulnerability poses a risk of unauthorized access to sensitive administrative data within FileMaker Server environments. Exposure of license details could reveal licensing terms and usage patterns, while access to application logs might disclose operational details, error messages, or user activity logs that could be leveraged for further attacks or reconnaissance. Organizations in sectors such as finance, healthcare, government, and critical infrastructure that rely on FileMaker Server for database management could face increased risk of data leakage or operational disruption. The ability for lower-privileged administrators to escalate their access undermines internal security controls and could facilitate insider threats or lateral movement by attackers who have compromised minimal privilege accounts. Although no exploits are known in the wild, the vulnerability’s presence in administrative interfaces makes it a valuable target for attackers seeking to gain deeper access without full credentials. The impact is heightened in environments where role assignments are not tightly controlled or where patch management is delayed.

1. Immediately upgrade all FileMaker Server instances to version 22.0.4 or later, where the vulnerability is fully addressed. 2. Conduct a thorough audit of all administrator roles and permissions within the FileMaker Server Admin Console to ensure that only necessary privileges are assigned, adhering strictly to the principle of least privilege. 3. Implement monitoring and alerting on administrative actions within the FileMaker Server environment to detect unusual access patterns or privilege escalations. 4. Restrict access to the Admin Console to trusted networks and enforce strong authentication mechanisms, such as multi-factor authentication, for all administrator accounts. 5. Regularly review and update patch management policies to ensure timely application of security updates. 6. Educate administrators on the risks of privilege escalation and the importance of secure role management. 7. Consider network segmentation to isolate FileMaker Server administrative interfaces from general user access to reduce attack surface.
