> Multiple unspecified vulnerabilities in Tenable Enclave Security versions before 1.9.0 require immediate patching.

CERT-FR has published an advisory documenting multiple vulnerabilities affecting Tenable Enclave Security versions prior to 1.9.0. The specific nature and impact of these vulnerabilities are not detailed in the advisory, with the vendor describing the risk as unspecified. Twenty CVEs are referenced spanning from 2023 through 2026, indicating a collection of historical and recently-discovered issues. Defenders using Enclave Security must upgrade to version 1.9.0 or later to remediate these issues.

The advisory directs organizations to Tenable's security bulletin tns-2026-23 for complete patch information and remediation guidance. Given the breadth of CVEs referenced and the lack of specific attack vector or impact details in the CERT-FR notice, organizations should treat this as a standard patch management priority for a security platform component.
