The CVE identifier CVE-2026-25840 was reserved by Fortinet on February 6, 2026, but the vulnerability entry has since been marked as REJECTED. This status indicates that the reported issue was either invalid, a duplicate, or otherwise not accepted as a valid security vulnerability by the CVE Numbering Authority. No technical details, affected product versions, or exploit information are provided. The lack of a CVSS score and patch links further suggests that this is not an active or confirmed vulnerability. Without concrete technical data, it is not possible to analyze attack vectors, impact, or mitigation strategies. The absence of known exploits in the wild reinforces the conclusion that this CVE does not currently pose a security risk.

Since CVE-2026-25840 is marked as REJECTED and lacks any technical details or evidence of exploitation, it does not present any known impact to organizations, including those in Europe. There is no indication of confidentiality, integrity, or availability risks associated with this entry. Therefore, European organizations are not at risk from this CVE and do not need to allocate resources to address it.

No specific mitigation actions are necessary for CVE-2026-25840 due to its rejected status and lack of technical details. Organizations should continue to follow standard security best practices, maintain up-to-date patching processes for their Fortinet and other security products, and monitor official advisories for any future valid vulnerabilities. If any new information emerges, it should be evaluated promptly.
