The French CERT has issued an advisory covering multiple vulnerabilities discovered in Cisco products. The affected products include Catalyst Center versions prior to 2.3.7.11-VA GSMU100 and 3.1.6 GSMU200, Secure Endpoint Connector for Mac (prior to 1.27.21), Linux (prior to 1.29.01), and Windows (prior to 8.6.21), as well as Secure Endpoint Private Cloud versions before 4.2.8.
The vulnerabilities enable attackers to conduct remote denial-of-service attacks and compromise data confidentiality. Eight CVEs have been assigned to these issues, spanning from CVE-2026-20191 through CVE-2026-20244. Cisco has released security bulletins addressing arbitrary file read vulnerabilities in Catalyst Center and multiple issues in ClamAV-based components.

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 16,445 reports from 149 sources, 666 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.
