- CISA lists CVE-2026-93616 as exploited in the wild.
NCSC-NL published an advisory for CVE-2026-93616, a pre-authentication directory-traversal vulnerability (CVSS 9.8) in the Check Point Management Web Service. The flaw allows unauthenticated attackers to execute arbitrary scripts from an arbitrary path, leading to remote code execution, and affects multiple Check Point Management and Logging components.
Check Point has confirmed active exploitation in the wild since 23 July 2026 and designated the issue a zero-day. Because the vulnerability is exploitable pre-authentication, exposure of the management interface to the internet significantly raises risk; Check Point specifically recommends restricting access to TCP/19009 to trusted IP addresses only. Check Point has released patches and published indicators of compromise to help organizations detect potential compromise.
Defenders running Check Point Security Management or Log Servers should apply the vendor updates immediately, restrict management interface access (particularly TCP/19009) to trusted networks, and check the published IoCs against logs for signs of prior exploitation dating back to July 2026.

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 16,436 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.
