Palo Alto Prisma Access Agent 24.x / 25.x / 26.x < 26.2.1 Multiple Vulnerabilities

high Nessus Plugin ID 314974

Synopsis

A ZTNA/SASE client installed on the remote host is affected by multiple vulnerabilities.

Description

The version of Palo Alto Networks Prisma Access Agent installed on the remote host is 24.x, 25.x, or 26.x prior to 26.2.1. It is, therefore, affected by multiple vulnerabilities:

 - Multiple information disclosure vulnerabilities allow a local user to access sensitive configuration data and credentials. (CVE-2026-0245)

 - A vulnerability with a privilege management mechanism enables a locally authenticated non-administrative user to escalate their privileges to root on macOS or NT AUTHORITY\SYSTEM on Windows, allowing arbitrary code execution and access to sensitive information otherwise accessible only to privileged accounts. (CVE-2026-0246)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Palo Alto Networks Prisma Access Agent version 26.2.1 or later.
