## Technical details

A security control bypass vulnerability exists in Prisma Access Agent for Linux due to improper protection of alternate paths (CWE-424). A local authenticated attacker with low privileges can exploit this flaw to route network traffic outside of the established VPN tunnel. This bypasses the intended security enforcement that ensures all traffic is encapsulated within the secure tunnel. The vulnerability is specific to the Linux agent and does not affect other operating systems. The issue is resolved in Prisma Access Agent for Linux version 26.2.1.
