CERT-FR has published an advisory covering multiple vulnerabilities in HPE Aruba Networking products, specifically affecting Instant On Switch models 1830, 1930, and 1960 running versions prior to 3.4.0, and Private 5G Core versions prior to 1.26.1.1. The flaws, tracked as CVE-2026-39803, CVE-2026-39806, CVE-2026-40912, and CVE-2026-44877, could allow an attacker to trigger a remote denial of service, compromise data confidentiality, or bypass security policies.
HPE has released two security bulletins (HPESBNW05038 and HPESBNW05077) alongside patches. No evidence of active exploitation is mentioned in the advisory; organizations running affected switch or 5G core software should apply the vendor-supplied fixes as part of routine patch management.

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.
