Lifecycle Timeline
5DescriptionCVE.org
A server-side request forgery (SSRF) vulnerability in the IKEv2 implementation of Palo Alto Networks PAN-OS® software allows an unauthenticated attacker to cause the firewall to send network requests to unintended destinations or cause a denial of service (DoS) condition.
Panorama, Cloud NGFW and Prisma® Access are not impacted by these vulnerabilities.
AnalysisAI
Server-side request forgery in the IKEv2 implementation of Palo Alto Networks PAN-OS allows unauthenticated remote attackers to coerce the firewall into issuing outbound network requests to arbitrary destinations or to trigger a denial-of-service condition. Affected are PAN-OS 10.2, 11.1, 11.2, and 12.1 branch trains; Panorama, Cloud NGFW, and Prisma Access are explicitly confirmed unaffected. No public exploit code has been identified and SSVC assessment confirms no current exploitation, though a vendor-released patch is available across all impacted branches.
Technical ContextAI
IKEv2 (Internet Key Exchange version 2, RFC 7296) is the protocol used to negotiate and establish IPsec VPN security associations, typically operating over UDP ports 500 and 4500. CWE-918 (Server-Side Request Forgery) arises when an application accepts attacker-controlled input and uses it - without adequate validation or allowlisting - to construct and issue outbound network requests from the server itself. In this case, the PAN-OS IKEv2 handler processes attacker-supplied protocol fields in a way that allows the firewall appliance to be directed to initiate connections to unintended hosts. This is particularly impactful on a network security device because the firewall often has privileged access to internal network segments that would otherwise be unreachable from external attackers, making SSRF a vector for internal reconnaissance. Affected CPEs include cpe:2.3:a:palo_alto_networks:pan-os:*:*:*:*:*:*:*:* across the 10.2, 11.1, 11.2, and 12.1 version trees per EUVD-2026-30105.
RemediationAI
The primary remediation is upgrading to a patched PAN-OS release. For PAN-OS 10.2, upgrade to 10.2.18-h6, 10.2.16-h7, 10.2.13-h21, 10.2.10-h36, or 10.2.7-h34 depending on the deployed minor version. For PAN-OS 11.1, upgrade to 11.1.15, 11.1.13-h5, 11.1.10-h25, 11.1.7-h6, 11.1.6-h32, or 11.1.4-h33. For PAN-OS 11.2, upgrade to 11.2.12, 11.2.10-h6, 11.2.7-h13, or 11.2.4-h17. For PAN-OS 12.1, upgrade to 12.1.7 or 12.1.4-h5. Full patch details and upgrade guidance are available from the vendor advisory at https://security.paloaltonetworks.com/CVE-2026-0258. As a compensating control where immediate patching is not possible, restrict inbound IKEv2 traffic (UDP 500 and UDP 4500) using upstream ACLs or zone-based policies to only known, trusted VPN peer IP addresses. This reduces the attacker-accessible attack surface but may impact legitimate VPN onboarding flows with dynamic peer IPs. Egress firewall rules limiting outbound connections from the management and dataplane to expected infrastructure can limit the practical SSRF reach while a patch is applied.
