## 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.
