However, the vulnerability entry is marked as 'REJECTED' and lacks detailed technical information, affected versions, patch links, or known exploits in the wild. The absence of a CVSS score and technical details indicates that this CVE identifier was likely reserved but later rejected, meaning it does not correspond to a confirmed or valid security vulnerability. Consequently, there is no substantive technical information available about the nature, mechanism, or impact of this supposed vulnerability.

Given that CVE-2023-51753 is marked as rejected and lacks any technical details or evidence of exploitation, there is no direct impact to analyze. European organizations are not at risk from this non-existent or invalid vulnerability. No systems or products have been identified as affected, and no attack vectors or consequences have been documented. Therefore, this CVE does not pose any threat to confidentiality, integrity, or availability of systems within Europe or elsewhere.

Since CVE-2023-51753 is a rejected CVE with no valid vulnerability associated, no specific mitigation actions are necessary.
