What to check
- Applies to
- The 3 CVEs named below. Whether you run an affected version is not assessed: check the versions the source lists.
- Exploitation
- CISA lists CVE-2026-123039 as exploited in the wild.
CERT-FR issued an advisory covering multiple vulnerabilities affecting several Check Point product lines, including Security Gateway, Security Management, Multi-Domain Security Management, Scalable Platforms, and Quantum Force Firewalls. The affected versions span the 81.x branch prior to 81.20 with patch 174, and the 82.x branch prior to 82.20 with patch 14. Three CVEs are referenced (CVE-2026-107484, CVE-2026-120490, CVE-2026-123039) corresponding to Check Point's own security bulletins (sk1000291, sk1000362, sk1000364) published on 12 November 2026.
The vulnerabilities allow an attacker to achieve privilege escalation and bypass security policy enforcement on affected devices. No details on exploitation complexity, prerequisites, or in-the-wild exploitation are provided in the advisory; CERT-FR simply relays the vendor bulletins and directs administrators to apply the vendor-supplied patches.
Defenders running any of the listed Check Point product versions should prioritize upgrading to the fixed releases (81.20 with patch 174 or 82.20 with patch 14) as referenced in the official Check Point security bulletins. No workarounds or detection guidance beyond patching are provided.

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 16,572 reports from 147 sources, 724 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.
