Multiple vulnerabilities in Tenable Enclave Security
Free public brief. The indicators, the detections with Splunk SPL already written (plus Elastic and KQL where they apply), and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.
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.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries its extracted indicators, its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply), the actors and CVEs it names as live profiles, and the vendor research on the same campaign — the primary source the news paraphrased, cited and read directly.
It sits in a corpus of 13,853 reports from 146 sources, 616 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
