CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-0310 Buffer overflow in the XML processing stack of Palo Alto Networks PAN-OS enables unauthenticated remote attackers to cause denial of service on VM-Series virtual firewalls or execute arbitrary code with root privileges on PA-Series physical appliances. The vulnerability is reachable via the management web interface or dataplane interface, and Panorama management platforms are also confirmed in scope. No public exploit has been identified at time of analysis; the CVSS 4.0 supplemental metric E:U corroborates no known active exploitation. HIGH 7.2 0.3% 36
CVE-2026-0294 Privilege escalation via an uncontrolled search path (CWE-427) in Palo Alto Networks Prisma Access Agent on Windows and macOS allows a local user to execute arbitrary code with elevated privileges. The vulnerability is platform-specific and explicitly does not affect the Linux, iOS, Android, or ChromeOS versions of the agent. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog; the CVSS 4.0 base score of 6.0 reflects the local-only attack vector, though the high confidentiality and integrity impact to the vulnerable system is significant for enterprise endpoint deployments. MEDIUM 6.0 0.1% 30
CVE-2026-0299 Local privilege escalation in Palo Alto Networks GlobalProtect app (Windows, macOS, and Linux) allows any local non-administrative user to gain NT AUTHORITY\SYSTEM on Windows or root on macOS and Linux via CWE-426 (Untrusted Search Path), enabling arbitrary command execution at the highest OS privilege level. The vulnerability is confirmed by Palo Alto Networks in their own advisory and affects desktop platforms only - iOS, Android, and Chrome OS are explicitly excluded. No public exploit code or active exploitation is confirmed at time of analysis; the CVSS 4.0 score of 5.9 Medium reflects the local-only attack vector requirement. MEDIUM 5.9 0.2% 30
CVE-2026-0307 Multiple local privilege escalation flaws in Palo Alto Networks GlobalProtect App on Windows, macOS, and Linux allow any authenticated local user to elevate privileges to NT AUTHORITY\SYSTEM or root. The root cause is CWE-426 (Untrusted Search Path), a class of vulnerability commonly manifesting as DLL search-order hijacking or PATH manipulation that the privileged VPN client process follows. No public exploit is known at time of analysis, and Palo Alto has released fixed versions; iOS, Android, and ChromeOS deployments are explicitly not affected. MEDIUM 5.9 0.1% 30
CVE-2026-0278 Multiple protection mechanism failures in the Data Loss Prevention (DLP) component of Palo Alto Networks Prisma Access Agent for Windows enable a local authenticated user to bypass DLP policy enforcement controls. Only the Windows platform is affected; the Prisma Access Agent for macOS is explicitly excluded per vendor advisory. No public exploit code or active exploitation has been identified at time of analysis, though the CVSS 4.0 supplemental urgency rating of Amber and high confidentiality/integrity impact on the vulnerable system make this a meaningful insider threat risk. MEDIUM 5.8 0.2% 29
CVE-2026-0306 DLP policy enforcement bypass in Palo Alto Networks Prisma Access Agent on Windows allows a low-privileged local user to circumvent configured EndPoint Data Loss Prevention controls and exfiltrate sensitive data that configured policy should block. The vulnerability is explicitly scoped to Windows deployments only - macOS, Linux, iOS, Android, and Chrome OS agents are confirmed unaffected by the vendor. No public exploit code is identified at time of analysis, and the CVSS 4.0 exploitation metric (E:U) indicates no observed active exploitation. MEDIUM 5.8 0.1% 29
CVE-2026-0277 Improper certificate validation in the Palo Alto Networks Prisma Access Agent for iOS exposes VPN tunnel traffic to interception and manipulation by a network-adjacent attacker. The flaw (CWE-295) enables a man-in-the-middle position to defeat the agent's TLS/certificate trust chain, allowing an adversary to read or alter traffic that the iOS client believes is securely tunneled. Exploitation is limited to iOS deployments - the Windows, macOS, Linux, Android, and ChromeOS agents are confirmed unaffected. No public exploit code exists and the vulnerability is not listed in the CISA KEV catalog. MEDIUM 5.7 0.1% 29
CVE-2026-0293 Anti-tamper protection bypass in Palo Alto Networks Prisma Access Agent on Windows allows a local administrator to gain unauthorized access to the agent's protected processes and files, effectively disabling endpoint security enforcement. Only the Windows platform is affected - Linux, macOS, iOS, Android, and Chrome OS deployments are explicitly not impacted. No public exploit code has been identified and no active exploitation has been confirmed (CVSS E:U), keeping real-world risk constrained to insider threat and post-compromise scenarios. MEDIUM 5.6 0.1% 28
CVE-2026-0298 Remote code execution in Palo Alto Networks GlobalProtect app on Windows allows a network-adjacent man-in-the-middle attacker to execute arbitrary code with SYSTEM privileges by exploiting improper input validation in the Pre-Logon Access Provider (PLAP) component (CWE-94). Only Windows deployments with the PLAP feature configured are affected; GlobalProtect on Linux, macOS, iOS, Android, and Chrome OS is explicitly excluded from the vulnerability scope. No public exploit code exists at time of analysis and the vulnerability is not listed in the CISA KEV catalog, but the SYSTEM-level code execution outcome before user logon warrants prioritized remediation for any enterprise Windows fleet using the pre-logon VPN feature. MEDIUM 5.2 0.2% 26
CVE-2026-0297 Out-of-bounds write in Palo Alto Networks GlobalProtect app exposes Windows, macOS, and Linux endpoints to arbitrary code execution at SYSTEM or root privilege levels when clients connect to an attacker-controlled rogue gateway or are subjected to a man-in-the-middle attack. The vulnerability resides in the client-side VPN agent's processing of gateway-supplied data, where a crafted response can corrupt memory and hijack execution. No public exploit has been identified at time of analysis, and CISA has not confirmed active exploitation, but full confidentiality, integrity, and availability compromise is possible on any affected endpoint that connects through a manipulated gateway. MEDIUM 5.2 0.2% 26
CVE-2026-0304 Privilege escalation to root on Palo Alto Networks Cortex XDR Broker VM is achievable by an authenticated low-privileged user who simultaneously holds a man-in-the-middle position on the adjacent network segment. The underlying flaw is argument injection (CWE-88), allowing the attacker to manipulate command-line arguments processed by the Broker VM to gain root-level code execution on the appliance. No public exploit has been identified (CVSS 4.0 E:U, Urgency: Amber), and Palo Alto Networks has published an advisory at security.paloaltonetworks.com. MEDIUM 4.8 0.2% 24
CVE-2026-0296 Improper certificate validation in Palo Alto Networks GlobalProtect app allows an unauthenticated attacker with an established man-in-the-middle network position to intercept and modify application-layer communications between the client and backend infrastructure. Affected platforms are desktop and non-mobile variants - iOS, Android, and Chrome OS deployments are explicitly confirmed unaffected. No public exploit code has been identified and this vulnerability is not listed in CISA KEV, though the confidentiality and integrity impacts are rated High given successful interception enables full visibility and manipulation of application traffic outside the VPN tunnel. MEDIUM 4.5 0.1% 23
CVE-2026-0305 Information disclosure in the Palo Alto Networks Prisma® Access Agent on Linux allows local low-privileged users to read sensitive configuration data and credentials stored by the agent process. Only the Linux platform is affected; Palo Alto Networks has explicitly confirmed that macOS, Windows, iOS, Android, and Chrome OS deployments are not impacted. No public exploit code and no active exploitation have been identified; the CVSS 4.0 vector carries an E:U (unexploited) modifier. MEDIUM 4.3 0.1% 22
CVE-2026-0295 Privilege escalation to root in Palo Alto Networks GlobalProtect App on macOS is enabled by a race condition exploitable by a locally authenticated, low-privileged user. The vulnerability is strictly macOS-specific - GlobalProtect on Linux, Windows, iOS, Android, and Chrome OS is explicitly not affected per vendor advisory. No public exploit has been identified at time of analysis, and the CVSS 4.0 score of 4.1 reflects the local, timing-dependent, and low-privilege-required nature of this attack. MEDIUM 4.1 0.1% 21
CVE-2026-0309 Command injection in Palo Alto Networks PAN-OS allows an authenticated administrator to escape CLI restrictions and execute arbitrary OS commands as root via CWE-78 weaknesses in the Luna Hardware Security Module integration pathway. Exploitation is doubly gated: the attacker must hold administrative credentials with CLI access, and the target device must be configured with a Luna HSM - a niche cryptographic hardware module rarely deployed outside regulated or high-assurance environments. Panorama, Cloud NGFW, and Prisma Access are explicitly confirmed unaffected; vendor-released patches exist across all supported PAN-OS branches, and no public exploit or active exploitation has been identified. MEDIUM 4.0 0.4% 20
