CERT-FR advises Microsoft product patches across multiple vectors
Free public brief. The indicators, the detections with Splunk SPL already written (plus Elastic and KQL where they apply), and a Slack alert the next time this touches a vendor you run are in the app — free account, no card.
CERT-FR advisory on 60 vulnerabilities spanning Exchange, SharePoint, Dynamics, Teams, and developer tools requiring immediate patching.
French CERT (CERT-FR) has published a security advisory covering multiple vulnerabilities discovered across a broad range of Microsoft products released on 11 August 2026. The affected products span enterprise infrastructure (Exchange Server, SharePoint Server), business applications (Dynamics 365 Business Central), collaboration platforms (Microsoft Teams), development tools (Visual Studio, Visual Studio Code), system utilities (PowerShell), and cloud services (OneDrive, Entra Connect, Microsoft Defender for Endpoint). The vulnerabilities enable remote code execution, privilege escalation, denial of service, data confidentiality and integrity breaches, and security policy bypass. Affected versions are detailed for each product line, with patch versions specified. This is a typical monthly patch advisory from the primary vendor authority; defenders must prioritize updates based on which products are deployed in their environment and the specific attack surface each presents.

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 its extracted indicators, its detections (Splunk SPL already written, plus Elastic and Microsoft KQL where they apply), the actors and CVEs it names as live profiles, and the vendor research on the same campaign — the primary source the news paraphrased, cited and read directly.
It sits in a corpus of 13,854 reports from 146 sources, 616 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. Name the vendors you run and Slack hears about the reports that touch them — about forty a week that are yours, not the four hundred that are not.
