What to check
- Applies to
- The 6 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- CISA lists CVE-2025-24983, CVE-2025-24984, CVE-2025-24985, CVE-2025-24991, CVE-2025-24993, and CVE-2025-26633 as exploited in the wild.
Japan's IPA issued an advisory highlighting Microsoft's March 2025 monthly security updates, which address multiple vulnerabilities across Windows products. Microsoft has confirmed that six of these flaws—CVE-2025-24983, CVE-2025-24984, CVE-2025-24985, CVE-2025-24991, CVE-2025-24993, and CVE-2025-26633—are being actively exploited in the wild, raising concerns of increased attacker activity targeting unpatched systems.
Successful exploitation of these vulnerabilities could allow attackers to crash applications, gain elevated privileges, or take control of affected machines. IPA urges both individual users and organizations to apply the security updates immediately via Windows Update, noting that some patches may require a system restart. The advisory does not name any specific threat actor, campaign, or malware associated with the exploitation, focusing instead on the urgency of patch deployment given confirmed active exploitation.

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.
