ANSSI (CERT-FR) published an advisory covering multiple vulnerabilities in Wireshark, the widely used network protocol analyzer. The flaws affect Wireshark versions in the 4.6.x branch prior to 4.6.7 and all versions prior to 4.4.17, and could allow an attacker to trigger a remote denial of service or compromise the confidentiality of processed data.
The issues are tracked across twelve separate CVE identifiers and correspond to twelve distinct Wireshark security bulletins (wnpa-sec-2026-52 through wnpa-sec-2026-63) published by the Wireshark Foundation on 9 July 2026. No exploitation in the wild is mentioned; the advisory is a standard vendor patch notification. Users are advised to apply the fixes referenced in the official Wireshark security bulletins.

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.
