CVE-2026-0301Network attack vector

Sensitive information disclosure via uninitialized resource

Published Aug 13, 2026 · Updated Aug 13, 2026

Information disclosure in PAN-OS 10.2 before 10.2.8 and 11.1 before 11.1.16-h1 allows remote attackers to obtain sensitive data. Custom URL Filtering HTML response pages that use variables beyond user, url, category, and pan_form can access an uninitialized resource; the vendor has not identified the resource or disclosed the exposed data. Exposure requires an imported custom response page and network access; Prisma Access 10.2 before 10.2.10 also requires authentication, while Cloud NGFW on AWS or Azure is affected except on version 11.2.
