The CVE-2026-25978 entry was reserved by Fortinet on February 9, 2026, but subsequently rejected, indicating that the vulnerability either was not confirmed or did not meet the criteria for inclusion in the CVE list. No technical details, affected product versions, or exploit information have been published. The lack of a CVSS score and absence of patch or mitigation guidance further suggest that this is not a valid or exploitable vulnerability. Without concrete information on the nature of the flaw, its impact, or affected systems, it is not possible to provide a detailed technical analysis or assess the threat landscape.

Since CVE-2026-25978 is a rejected entry with no known exploits or affected products, it currently poses no identifiable risk to organizations, including those in Europe. There is no evidence that this vulnerability could impact confidentiality, integrity, or availability of systems. Therefore, European organizations are not at risk from this CVE at this time.

No specific mitigation measures are applicable due to the absence of a confirmed vulnerability or affected products. Organizations should continue to follow standard security best practices and monitor official advisories from Fortinet and other trusted sources for any future updates or valid vulnerabilities.
