CVE-2025-54355 is a vulnerability entry that was reserved on July 21, 2025, and assigned by Fortinet. However, the CVE record is marked as REJECTED, indicating that after review, this entry was determined not to represent a valid or exploitable security vulnerability. There are no technical details, affected versions, or exploit information available. No CVSS score has been assigned, and no patches or mitigations have been published. The absence of any descriptive data or indicators suggests that this CVE identifier was either a duplicate, a false positive, or otherwise invalidated by the CVE assignment authority. Consequently, there is no actionable threat or vulnerability information to analyze or mitigate.

Since the CVE entry is rejected and no valid vulnerability details exist, there is no impact on confidentiality, integrity, or availability to consider. European organizations are not at risk from this non-existent vulnerability, and no operational or security impact is expected.

No specific mitigation is required because the vulnerability has been rejected and does not represent a real threat. Organizations should continue to follow standard security best practices and maintain up-to-date software and firmware for their Fortinet products or any other relevant systems. Monitoring official advisories from Fortinet and trusted vulnerability databases remains recommended to stay informed about legitimate threats.
