CVE-2025-54845 is a vulnerability identifier that was reserved but subsequently marked as REJECTED by the assigner, Fortinet, according to the CVE Database V5. The available information lacks any technical details, description, affected versions, or exploit data. No CVSS score has been assigned, and there are no known exploits in the wild. The absence of technical details and the REJECTED status indicate that this CVE entry does not correspond to a confirmed or valid security vulnerability. It may have been reserved prematurely or invalidated after review. Consequently, there is no substantive information about the nature of the vulnerability, its attack vector, or potential impact on systems or networks.

Given the REJECTED status and lack of technical details, there is no evidence that this CVE represents a genuine security threat. Therefore, it poses no known risk or impact to European organizations or any other entities. Without a valid vulnerability, there is no confidentiality, integrity, or availability impact to consider. Organizations do not need to take any action related to this CVE, as it does not represent an exploitable security issue.

Since CVE-2025-54845 is a rejected and unconfirmed vulnerability, no specific mitigation measures are necessary. Organizations should continue to follow standard cybersecurity best practices, including timely patching of confirmed vulnerabilities, network monitoring, and incident response readiness. It is advisable to monitor official vulnerability databases and vendor advisories for any future updates or valid vulnerabilities related to Fortinet products or other systems in use.
