CERT-FR has published an advisory covering multiple vulnerabilities discovered in Microsoft Edge versions prior to 150.0.4078.48. The flaws span a broad range of impact categories including remote code execution, privilege escalation, data confidentiality breaches, SSRF, XSS, and security policy bypass. Microsoft Edge users running affected versions face risk of arbitrary code execution and unauthorized system access if a malicious actor exploits these weaknesses. The advisory references individual Microsoft Security Response Center (MSRC) bulletins published on 2–3 July 2026 for each CVE, directing organizations to consult the official patches. No active exploitation in the wild is reported in this advisory, but the breadth and severity of the flaws warrant immediate update to version 150.0.0.4078.48 or later.

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 16,433 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.
