What to do

Use the vendor's fixed-version matrix and upgrade affected firewalls. Preserve a technical support file before upgrading a suspected compromised device, and follow the vendor's recovery guidance rather than assuming a patch removes an existing compromise.

CISA's required action: Apply mitigations per vendor instructions as they become available. Otherwise, users with vulnerable versions of affected devices should enable Threat Prevention IDs available from the vendor. See the vendor bulletin for more details and a patch release schedule.

About this data

This record was assembled editorially. Editorial review: Oct 26, 2026. Editorial selection does not make a reported claim independently confirmed.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
