Palo Alto Networks published a group of security advisories on Wednesday, November 11, adding a fresh product-risk issue ahead of its fiscal first-quarter results. The company's Security Advisories page listed ten entries for the period.
Panorama flaw leads disclosures
The highest-rated PAN-OS entry was CVE-2026-0331, a sensitive-information-disclosure vulnerability with a CVSS score of 6.6. It affects listed releases across PAN-OS 10.2 through 12.2 and Prisma Access versions, while the advisory identifies fixed releases for the affected branches.
A second prominent entry, CVE-2026-0330, concerns authenticated remote code execution in Panorama and carries a CVSS score of 6.1. The advisory lists affected Panorama installations across several PAN-OS release lines and identifies fixed builds, making patch adoption the immediate operational response for customers using the centralized management platform.
The same publication also covers a Chromium update for Prisma Browser with a CVSS score of 7.7, as well as privilege-management, buffer-overflow, impersonation, authorization-bypass and privilege-escalation issues across the company's product portfolio. The entries do not establish a financial impact for Palo Alto Networks, but they raise the importance of remediation and customer communication before the next results update.
Results remain the next catalyst
Palo Alto Networks has scheduled its fiscal first-quarter 2027 results for after the U.S. market close on Wednesday, November 18. The company plans a webcast at 4:30 p.m. Eastern time, according to its November 3 announcement.
