CVE-2025-61854 is a vulnerability entry that has been reserved but subsequently marked as REJECTED by the assigner, Fortinet. The available information lacks any technical details, affected versions, or descriptions of the vulnerability. No CVSS score has been assigned, and there are no known exploits in the wild. The absence of technical details and the REJECTED status typically indicate that the vulnerability was either a duplicate, invalid, or otherwise not accepted as a valid security issue by the responsible authority. Consequently, there is no actionable information about the nature of the vulnerability, its attack vector, or potential impact.

Given the lack of any technical details, affected products, or exploit information, there is no evidence to suggest any impact on European organizations or any other entities. Since the vulnerability is marked as REJECTED and no exploits are known, it does not pose a threat to confidentiality, integrity, or availability of systems. Therefore, no direct impact can be assessed for European organizations or their critical infrastructure.

As this CVE entry is rejected and lacks any technical details or affected versions, no specific mitigation steps can be recommended. Organizations should continue to follow standard cybersecurity best practices, including timely patching of legitimate vulnerabilities, network segmentation, and monitoring for suspicious activity. It is also advisable to stay updated with official advisories from Fortinet and other vendors for valid vulnerabilities.
