ANSSI (the French national cybersecurity agency) issued an advisory covering twelve vulnerabilities affecting Microsoft Edge versions prior to 151.0.4129.101. The advisory does not specify the exact nature of the security impact, stating only that exploitation could allow an attacker to cause an unspecified security issue, per Microsoft's own bulletin language. No details on exploitation status, attack vectors, or proof-of-concept availability are provided in this advisory.
Each vulnerability is tracked under its own CVE identifier (CVE-2026-76033, -76034, -76035, -76037, -76038, -76040, -76041, -76042, -76043, -76044, -76045, and -76047), all published by Microsoft on 20 August 2026. Organizations running affected Edge versions should apply the vendor-supplied updates referenced in the Microsoft Security Response Center bulletins as soon as feasible. This is a routine vendor patch advisory rerun by ANSSI, with no indication of active exploitation or targeted campaigns.

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.
