CERT-FR flags dozens of Tenable Network Monitor flaws
Free public brief. Slack alerts on the vendors you run come with the paid plans, and a new account gets three days of them, no card.
CERT-FR warns of over 90 vulnerabilities in Tenable Network Monitor before 6.6.0, including remote code execution, DoS, SSRF and data exposure risks.
CERT-FR has published an advisory covering a large batch of vulnerabilities affecting Tenable Network Monitor versions prior to 6.6.0. The flaws, documented in Tenable's own security bulletin tns-2026-32 (26 October 2026), span a wide range of impact categories including remote arbitrary code execution, remote denial of service, loss of data confidentiality and integrity, security policy bypass, and server-side request forgery (SSRF). Given the sheer number of CVEs referenced (over 90), these likely stem from bundled third-party components and libraries within the product rather than a single root cause.
No detail is provided on exploitation status, proof-of-concept availability, or specific attack vectors for any individual CVE; the advisory is a standard vulnerability notification directing readers to the vendor bulletin for patches. Defenders running Tenable Network Monitor should prioritize upgrading to version 6.6.0 or later and consult the vendor bulletin for any available workarounds or configuration mitigations for the highest-impact issues (particularly those enabling remote code execution or SSRF).

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 live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 14,359 reports from 144 sources, 627 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. Slack alerts are a paid-plan feature: 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.
