The CVE identifier CVE-2025-66183 was reserved but subsequently marked as REJECTED by the assigner, Fortinet. The entry contains no technical details, affected product versions, or exploit information. No CVSS score has been assigned, and there are no known exploits in the wild. The lack of CWE classification and patch links further indicates that this is not an active or recognized vulnerability. The rejection status typically means that the CVE was either a duplicate, invalid, or did not meet the criteria for assignment. Consequently, there is no substantive technical information to analyze or assess.

Given the rejection status and absence of technical details, there is no evidence of any impact on confidentiality, integrity, or availability. No affected systems or products have been identified, and no exploitation has been reported. Therefore, the threat does not pose any known risk to European organizations or any other entities at this time.

Since CVE-2025-66183 is a rejected and unsubstantiated entry, no specific mitigation actions are necessary. Organizations should continue to follow standard security best practices and maintain up-to-date patching for all software and hardware. Monitoring official advisories from vendors and trusted sources remains essential to respond promptly to valid vulnerabilities.
