France's CERT-FR has published an advisory regarding multiple vulnerabilities discovered in Microsoft Edge browser versions prior to 149.0.4022.96. The vulnerabilities enable remote arbitrary code execution and include additional security issues not yet specified by the vendor. Microsoft released patches on June 26, 2026, addressing 23 distinct CVEs spanning the CVE-2026-11647 through CVE-2026-50521 range.
The advisory provides references to individual Microsoft Security Response Center bulletins for each CVE, allowing organizations to review technical details and apply appropriate mitigations. No active exploitation or threat actor attribution is mentioned in the French government's notification.
Organizations running affected Microsoft Edge versions should prioritize updating to version 149.0.4022.96 or later to remediate these vulnerabilities. The presence of remote code execution vectors makes timely patching important for maintaining browser security posture.

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.
