Prisma Access Agent Privilege and Bypass Vulnerabilities

Privilege escalation via an uncontrolled search path (CWE-427) in Palo Alto Networks Prisma Access Agent on Windows and macOS allows a local user to execute arbitrary code with elevated privileges. The vulnerability is platform-specific and explicitly does not affect the Linux, iOS, Android, or ChromeOS versions of the agent. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog; the CVSS 4.0 base score of 6.0 reflects the local-only attack vector, though the high confidentiality and integrity impact to the vulnerable system is significant for enterprise endpoint deployments.

Anti-tamper protection bypass in Palo Alto Networks Prisma Access Agent on Windows allows a local administrator to gain unauthorized access to the agent's protected processes and files, effectively disabling endpoint security enforcement. Only the Windows platform is affected - Linux, macOS, iOS, Android, and Chrome OS deployments are explicitly not impacted. No public exploit code has been identified and no active exploitation has been confirmed (CVSS E:U), keeping real-world risk constrained to insider threat and post-compromise scenarios.

Authentication bypass in the Windows network driver of Palo Alto Networks Prisma Access Agent allows a local administrator to circumvent the agent's security inspection enforcement, subsequently enabling injection and interception of arbitrary network traffic. Only the Windows platform is affected - Linux, macOS, iOS, Android, and Chrome OS deployments are explicitly confirmed unaffected by the vendor. No public exploit has been identified at time of analysis, and exploitation requires pre-existing local administrator access, significantly narrowing the realistic threat population.

Symlink-following (CWE-59) in Palo Alto Networks Prisma Access Agent on Linux allows a local low-privileged user to delete a limited set of system files and disable the agent entirely. Only Linux deployments are affected - macOS, Windows, iOS, Android, and Chrome OS are explicitly confirmed safe by the vendor. No public exploit code or active exploitation (CISA KEV) has been identified; the CVSS 4.0 supplemental vector classifies exploitation as unlikely (E:U) with Amber urgency, making this a low-priority but genuine patch target for Linux endpoint fleets.
