Palo Alto Networks PAN-OS contains an authentication bypass vulnerability that allows attackers to bypass security restrictions and establish an unauthorized VPN connection. Required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
CISA KEV ↗ · unattributed attributionPalo Alto Networks PAN-OS contains an out-of-bounds write vulnerability in the User-ID Authentication Portal (aka Captive Portal) service that can allow an unauthenticated attacker to execute arbitrary code with root privileges on the PA-Series and VM-Series firewalls by sending specially crafted packets. Required action: Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable. Until the vendor releases an official fix, the following workaround should be implemented: - Restrict User-ID Authentication Portal access to only trusted zones. - Disable User-ID Authentication Portal if not required. 5/13/2026: Palo Alto has released a variety of patches. If these are relevant to your environment, please apply the designated patch.
CISA KEV ↗ · unattributed attributionPalo Alto Networks PAN-OS contains an external control of file name or path vulnerability. Successful exploitation enables an authenticated attacker with network access to the management web interface to read files on the PAN-OS filesystem that are readable by the “nobody” user. Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
CISA KEV ↗ · unattributed attributionPalo Alto Networks PAN-OS contains an authentication bypass vulnerability in its management web interface. This vulnerability allows an unauthenticated attacker with network access to the management web interface to bypass the authentication normally required and invoke certain PHP scripts. Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
CISA KEV ↗ · unattributed attributionPalo Alto Networks PAN-OS contains a vulnerability in parsing and logging malicious DNS packets in the DNS Security feature that, when exploited, allows an unauthenticated attacker to remotely reboot the firewall. Repeated attempts to trigger this condition will cause the firewall to enter maintenance mode. Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
CISA KEV ↗ · unattributed attributionPalo Alto Networks PAN-OS contains an OS command injection vulnerability that allows for privilege escalation through the web-based management interface for several PAN products, including firewalls and VPN concentrators. Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. Additionally, the management interfaces for affected devices should not be exposed to untrusted networks, including the internet.
CISA KEV ↗ · unattributed attributionPalo Alto Networks PAN-OS contains an authentication bypass vulnerability in the web-based management interface for several PAN-OS products, including firewalls and VPN concentrators. Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable. Additionally, management interface for affected devices should not be exposed to untrusted networks, including the internet.
CISA KEV ↗ · unattributed attributionPalo Alto Networks Expedition contains a SQL injection vulnerability that allows an unauthenticated attacker to reveal Expedition database contents, such as password hashes, usernames, device configurations, and device API keys. With this, attackers can also create and read arbitrary files on the Expedition system. Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
CISA KEV ↗ · unattributed attributionPalo Alto Networks Expedition contains an OS command injection vulnerability that allows an unauthenticated attacker to run arbitrary OS commands as root in Expedition, resulting in disclosure of usernames, cleartext passwords, device configurations, and device API keys of PAN-OS firewalls. Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
CISA KEV ↗ · unattributed attributionPalo Alto Networks Expedition contains a missing authentication vulnerability that allows an attacker with network access to takeover an Expedition admin account and potentially access configuration secrets, credentials, and other data. Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
CISA KEV ↗ · unattributed attributionPalo Alto Networks PAN-OS GlobalProtect feature contains a command injection vulnerability that allows an unauthenticated attacker to execute commands with root privileges on the firewall. 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.
CISA KEV ↗ · unattributed attributionA Palo Alto Networks PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected and amplified TCP denial-of-service (RDoS) attacks. Required action: Apply updates per vendor instructions.
CISA KEV ↗ · unattributed attributionPalo Alto Networks PAN-OS contains multiple, unspecified vulnerabilities which can allow for remote code execution when chained. Required action: Apply updates per vendor instructions.
CISA KEV ↗ · unattributed attributionPalo Alto Networks PAN-OS contains a vulnerability in SAML which allows an attacker to bypass authentication. Required action: Apply updates per vendor instructions.
CISA KEV ↗ · unattributed attributionRemote Code Execution in PAN-OS with GlobalProtect Portal or GlobalProtect Gateway Interface enabled. Required action: Apply updates per vendor instructions.
