CVE-2026-0250: CWE-787 Out-of-bounds Write in Palo Alto Networks GlobalProtect App
CVE-2026-0250 is a medium severity buffer overflow vulnerability in the Palo Alto Networks GlobalProtect app versions 6.2.0 and 6.3.0 (excluding iOS). It allows a man-in-the-middle attacker to disrupt system processes and potentially execute arbitrary code with SYSTEM privileges during the processing of Portal and Gateway communications. There is no known exploit in the wild and no official patch or remediation guidance currently available.
AI Analysis
Technical Summary
This vulnerability (CWE-787) is an out-of-bounds write in the Palo Alto Networks GlobalProtect app affecting versions 6.2.0 and 6.3.0. It occurs during the handling of requests and responses exchanged between the Portal and Gateway components. Exploitation could enable an attacker positioned as a man-in-the-middle to disrupt system processes or execute arbitrary code with SYSTEM-level privileges. The iOS version of the app is not affected. The CVSS 4.0 base score is 5.2, reflecting medium severity with attack vector requiring adjacent network access and no user interaction needed.
Potential Impact
Successful exploitation can lead to disruption of system processes and potential arbitrary code execution with SYSTEM privileges on affected GlobalProtect app installations (non-iOS). This could compromise the security and stability of the affected systems. There are no reports of active exploitation in the wild at this time.
Mitigation Recommendations
Patch status is not yet confirmed — check the Palo Alto Networks vendor advisory for current remediation guidance. Since no official fix or temporary mitigation is currently documented, users should monitor vendor communications for updates. The iOS GlobalProtect app is not affected by this vulnerability.
