CVE-2026-0282: CWE-20 Improper Input Validation in Palo Alto Networks Cloud NGFW
A file deletion vulnerability in Palo Alto Networks PAN-OS® software enables an unauthenticated attacker with network access to the management web interface to delete files from a temporary directory. The security risk posed by this issue is minimized by restricting access to the management web interface to only trusted internal IP addresses according to our recommended best practice deployment guidelines https://live.paloaltonetworks.com/t5/community-blogs/tips-amp-tricks-how-to-secure-the-management-access-of-your-palo/ba-p/464431 . This issue is applicable to PAN-OS software on PA-Series and VM-Series firewalls and on Panorama (virtual and M-Series). Cloud NGFW and Prisma® Access are not impacted by this vulnerability.

Technical Summary
This vulnerability involves improper input validation (CWE-20) in the PAN-OS management web interface, enabling unauthenticated network attackers to delete files from a temporary directory. It affects PAN-OS on PA-Series, VM-Series firewalls, and Panorama (virtual and M-Series). Cloud NGFW and Prisma Access are not affected. The vulnerability has a CVSS 4.0 base score of 2.7 (low severity). No official patch or remediation level has been provided yet. Palo Alto Networks recommends restricting access to the management interface to trusted internal IP addresses to minimize risk.
Potential Impact
An unauthenticated attacker with network access to the management web interface can delete files from a temporary directory, potentially disrupting management operations. However, the impact is limited by the low CVSS score and the recommended best practice of restricting management interface access to trusted internal IPs. There are no known exploits in the wild.
Mitigation Recommendations
No official patch or remediation level is currently provided. Palo Alto Networks advises restricting access to the management web interface to trusted internal IP addresses as a best practice to minimize risk. Monitor the vendor advisory for updates on patch availability.
