The provided information pertains to a reported vulnerability identified as CVE-2025-61890. However, the entry is marked with a 'REJECTED' state and lacks detailed technical information such as affected versions, vulnerability description, exploitation details, or patch information. The CVE is assigned by Fortinet but no CVSS score or exploit data is available, and no known exploits in the wild have been reported. The absence of technical details and the rejection status typically indicate that the CVE entry was either a duplicate, invalid, or otherwise not accepted as a valid vulnerability by the CVE authorities. Therefore, there is no substantive technical data to analyze regarding the nature, mechanism, or impact of this vulnerability.

Given the rejection status and lack of technical details, there is no evidence that this vulnerability poses any actual risk or impact to organizations, including those in Europe. Without confirmed affected products, attack vectors, or exploitation methods, it is not possible to assess any potential confidentiality, integrity, or availability impacts. Consequently, European organizations are not expected to be affected by this CVE entry.

Since the CVE entry is rejected and no vulnerability details are provided, no specific mitigation actions are warranted. Organizations should continue to follow standard cybersecurity best practices, including maintaining up-to-date software and monitoring vendor advisories for any legitimate vulnerabilities. If Fortinet or other vendors release official patches or advisories related to this or similar CVEs in the future, those should be promptly reviewed and applied.
