CVE-2025-57718 is a reported vulnerability identifier that was reserved on August 18, 2025, and assigned by Fortinet. However, the CVE entry is marked as REJECTED, indicating that after review, the vulnerability was either invalid, a duplicate, or otherwise not accepted as a valid security issue in the CVE database. There are no technical details, affected versions, or exploit information available. No CVSS score has been assigned, and no known exploits exist in the wild. The lack of technical details and the rejection status strongly suggest that this is not an active or valid security threat. Without concrete information on the nature of the vulnerability, affected products, or attack vectors, it is not possible to provide a detailed technical explanation or impact analysis.

Given the rejection status and absence of technical details, there is no evidence that this vulnerability poses any risk to organizations, including those in Europe. No impact on confidentiality, integrity, or availability can be assessed. Consequently, European organizations are not at risk from this CVE entry.

No specific mitigation actions are required since the CVE has been rejected and does not represent a valid vulnerability. Organizations should continue to follow standard security best practices and keep their systems updated with official patches from vendors. Monitoring official advisories from Fortinet and other trusted sources remains recommended.
