Exploitation
No exploitation in the wild and no public exploit is recorded for the CVEs named.

ANSSI-CERT-FR published an advisory covering multiple vulnerabilities in LibreNMS, an open-source network monitoring platform, affecting all versions prior to 26.5.0. The flaws allow attackers to achieve remote code execution, perform server-side request forgery (SSRF), and inject indirect remote cross-site scripting (XSS) attacks. These issues were disclosed via seven separate GitHub security advisories on August 4, 2026, and tracked under CVE-2026-45694.

No evidence of active exploitation is mentioned in the advisory. Administrators running LibreNMS should apply the vendor's patches by upgrading to version 26.5.0 or later as referenced in the official security bulletins.

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.

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 16,436 reports from 149 sources, 661 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, not the rest of the week's. Nothing is charged unless you subscribe.
