CERT-FR flags multiple Nessus vulnerabilities
Free public brief. The indicators, the detections with Splunk and KQL already written, and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.
CERT-FR warns of multiple Tenable Nessus flaws before 10.12.5 enabling SQL injection, data exposure, integrity loss and remote denial of service.
CERT-FR published an advisory covering nine CVEs affecting Tenable Nessus versions prior to 10.12.5. The vulnerabilities span SQL injection, remote denial of service, and breaches of data confidentiality and integrity, as detailed in Tenable's own security bulletin tns-2026-26 published 1 October 2026. No exploitation in the wild is mentioned in the advisory.
Defenders running Nessus should prioritize upgrading to version 10.12.5 or later as referenced in the vendor bulletin. No indicators of compromise, threat actors, or active campaigns are associated with this disclosure; it is a standard vulnerability advisory requiring patch management action.

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 with the Splunk SPL and Microsoft KQL already written, 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 10,646 reports from 152 sources, 506 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.
