## 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-2026-109618 and CVE-2026-109619 as exploited in the wild.

CERT-FR has issued an advisory detailing multiple vulnerabilities in Palo Alto Networks PAN-OS that allow an attacker to achieve remote arbitrary code execution. The advisory covers a wide range of affected PAN-OS branches, including versions 10.2.x, 11.1.x, 11.2.x, 12.1.x and 12.2.x prior to specific hotfix levels. Palo Alto Networks has confirmed that two of the associated CVEs, CVE-2026-109618 and CVE-2026-109619, are being actively exploited in the wild, while a third, CVE-2026-115560, is also referenced without confirmed exploitation status.

This advisory follows a prior CERT-FR alert (CERTFR-2026-ALE-014) issued on 21 October 2026, indicating the exploitation activity was already under heightened monitoring before this bulletin. Defenders running PAN-OS should prioritize patching to the listed fixed hotfix versions immediately given confirmed in-the-wild exploitation, and monitor firewall/management interfaces for signs of compromise. Some patches remain pending release for a subset of older branches (12.1.4-h13, 12.1.10-h3, 11.2.4-h23, 11.1.7-h12, 10.2.7-h39, 10.2.10-h42), requiring interim mitigations per vendor guidance until official fixes are published.
