What to check
- Applies to
- The 23 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- No exploitation in the wild and no public exploit is recorded for the CVEs named.
CERT-FR (the French national CSIRT) published an advisory referencing 21 CVEs affecting Microsoft Edge versions prior to 152.0.4191.62. The bulletin does not detail the specific vulnerability types or exploitation vectors, stating only that the vendor has not specified the risk category and that the flaws could allow an attacker to cause an unspecified security impact. This is a standard aggregation-style advisory pointing to Microsoft's own security update guide entries for each CVE, rather than original research.
No indicators of compromise, exploitation in the wild, or threat actor attribution are mentioned. Organizations running affected Edge versions should apply the vendor-supplied patches referenced in the Microsoft Security Response Center (MSRC) update guide entries for each listed CVE. As is typical for CERT-FR advisories of this nature, the recommended action is straightforward patching rather than active threat hunting.

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.
