CNA: palo_altoGlobalProtect App: Improper Certificate Validation Leads to Privilege Escalation
03 Exploitation and scoring
SRC: CISA, FIRST, NVD, RED HAT- Exploitation
- Assessed, none found. CISA's assessment recorded neither public exploit code nor evidence of exploitation when it was made.
- SSVC decision
- ExploitationnoneCISA recorded no public exploit code and no evidence of exploitation.
- AutomatablenoAt least one step from reconnaissance to exploitation cannot be reliably automated.
- Technical ImpacttotalSuccessful exploitation gives total control of the vulnerable component.
CISA publishes the decision points, not a final SSVC decision. The decision also depends on mission and well-being impact, which is a property of your deployment rather than of the vulnerability.- EPSS probability
- 0.11% probability of exploitation activity in the next 30 days.
- EPSS percentile
- Ranks above 1.6% of scored records. A rank, not a probability.
- NVD base score
- 5.3 (CVSS v4.0), scored by the NVD independently of the CNA.
- NVD CVSS vector
- CVSS:4.0/AV:P/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:N/R:U/V:D/RE:X/U:Amber
- NVD analysis status
- Deferred. NVD last modified this record on 2026-06-17.
- Red Hat severity
- No Red Hat rating. Red Hat rates the CVEs that affect its products.
Exploit-prediction scores from FIRST. Independent scoring and analysis status from the NVD. Vendor severity from Red Hat. Exploitation assessment and catalog membership from CISA.

* In addition to the software updates listed above, additional steps are required to protect against this vulnerability as described below:
Solution for new and existing GlobalProtect app installation on Windows / Linux
* Ensure the portal/gateway certificate can be validated using the operating system's certificate store (e.g., Local Machine Certificate Store or Current User Certificate Store in Windows; for Linux, refer to this documentation https://docs.paloaltonetworks.com/globalprotect/6-2/globalprotect-app-user-guide/globalprotect-app-for-linux/support-for-native-certificate-store-for-prisma-access-and-globalprotect-app ).
* Remove any certificates associated with portal/gateway validation from the "Trusted Root CA" list on the Portal.
* Enable portal
