CVE-2026-0299 — GlobalProtect App: Local Privilege Escalation Vulnerabilities
Local privilege escalation vulnerabilities in the Palo Alto Networks GlobalProtect™ app enable a local user to escalate their privileges to NT AUTHORITY\SYSTEM on Windows, and root on macOS and Linux. This enables a non-administrative user to execute arbitrary commands with administrative privileges. The GlobalProtect app on iOS, Android, and Chrome OS is not affected.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- Technical severity (high)+6
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
First 24 hours
Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.
- Identify exposed assets running the affected vendor/product/version combinations (Palo Alto Networks Globalprotect, Palo Alto Networks GlobalProtect App).
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.
