Palo Alto Networks stock faces new PAN-OS risks before earnings

On Wednesday, November 11, Palo Alto Networks published a new security advisory for PAN-OS and Prisma Access. The disclosure adds a fresh product-risk issue as the company approaches its fiscal first-quarter results.

The Palo Alto Networks Security Advisories page rates CVE-2026-0331 at severity 6.6. The issue can allow an unauthenticated attacker with network access to obtain sensitive firewall and session information through a dataplane interface.

Patch thresholds set across releases

The advisory covers PAN-OS versions from 10.2 through 12.2, as well as Prisma Access 10.2, 11.2 and 12.1. Palo Alto Networks lists fixed builds for the affected branches and says that no special configuration is required for exposure.

The company says it is not aware of malicious exploitation of the issue. It also states that Panorama is not affected, while Cloud NGFW and Prisma Access customers will receive upgrades during scheduled maintenance cycles or can request an earlier upgrade window.

Earnings remain the next checkpoint

Palo Alto Networks is scheduled to release fiscal first-quarter 2027 results after the U.S. market close on Wednesday, November 18. The webcast is planned for 4:30 p.m. Eastern time, leaving remediation progress and platform execution as near-term investor focus areas.
