CVE-2026-0285 in PAN-OS
Summary
by MITRE • 07/09/2026
A server-side request forgery (SSRF) vulnerability in Palo Alto Networks PAN-OS software enables an authenticated administrator with network access to the management web interface to make unauthorized requests from the firewall to internal services.
The security risk posed by this issue is minimized when the management interface is restricted to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 .
Panorama, Cloud NGFW, and Prisma® Access are not impacted by this vulnerability.

This server-side request forgery vulnerability in Palo Alto Networks PAN-OS software represents a critical security flaw that undermines the integrity of network protection mechanisms. The vulnerability specifically affects authenticated administrators who possess access to the management web interface, creating a pathway for malicious actors to leverage legitimate administrative privileges to make unauthorized requests from the firewall to internal services. This type of vulnerability falls under the CWE-918 category, which encompasses server-side request forgery conditions where applications fail to properly validate or sanitize user-supplied input that influences network requests. The flaw essentially allows an attacker to bypass normal access controls and potentially access internal systems that should remain isolated from external or unauthorized administrative access.
The operational impact of this vulnerability extends beyond simple privilege escalation as it creates a potential attack vector for lateral movement within network environments. When an authenticated administrator accesses the management interface, the malicious actor can manipulate the application to make requests to internal services that the firewall itself has access to but should not be reachable through administrative interfaces. This presents a significant risk particularly in environments where administrative access is considered privileged and restricted. The vulnerability's exploitation could lead to unauthorized data access, service disruption, or even complete compromise of internal infrastructure, as the attacker leverages legitimate administrative credentials to gain access to resources that normally would be protected by network segmentation.
The security implications are further amplified when considering that this vulnerability specifically targets the management interface of PAN-OS software, which serves as the central control point for firewall operations and policy enforcement. The recommended best practice deployment guidelines emphasize restricting management interface access to only trusted internal IP addresses, a mitigation strategy that aligns with the principle of least privilege and network segmentation concepts found in various cybersecurity frameworks including the NIST Cybersecurity Framework. This restriction approach directly addresses the vulnerability by limiting the attack surface and preventing unauthorized access attempts from untrusted networks or systems. Organizations implementing this mitigation strategy significantly reduce their exposure to potential exploitation, as the vulnerability requires both authentication and direct network access to the management interface.
The fact that Panorama, Cloud NGFW, and Prisma Access remain unaffected provides some comfort regarding the scope of impact but does not eliminate the need for comprehensive security measures across all deployed PAN-OS components. This distinction highlights the importance of understanding how different products within a vendor's portfolio may be vulnerable or protected based on their specific implementation details and architectural design. The vulnerability's characteristics align with ATT&CK technique T1078 which involves valid accounts and privilege escalation, demonstrating how legitimate administrative access can be abused to perform unauthorized actions. Organizations should implement additional monitoring and logging controls around management interface access, particularly when administrators make requests that involve internal service communications, as this behavior could indicate exploitation attempts.
Effective mitigation requires a multi-layered approach combining network segmentation, access control restrictions, and continuous monitoring of administrative activities. The recommended practice of limiting management interface access to trusted IP addresses serves as both a preventive measure against this specific vulnerability and a general security enhancement. Organizations should also consider implementing additional controls such as network access control lists, intrusion detection systems, and regular security assessments to detect potential exploitation attempts. Regular updates and patches from Palo Alto Networks remain critical for maintaining protection against known vulnerabilities, while comprehensive security awareness training for administrators helps prevent social engineering attacks that might lead to unauthorized access. The vulnerability underscores the importance of maintaining strict separation between management interfaces and operational network traffic, ensuring that administrative functions do not inadvertently provide access to internal services without proper authorization controls in place.
