Official Description
An improper protection of alternate path vulnerability in Palo Alto Networks Prisma® Browser on macOS fails to properly restrict access to an internal automation bridge. This allows a locally authenticated non-admin user to leverage an exposed communication channel to send unauthorized commands to the browser, bypassing security controls.
Technical Analysis
CVE-2026-0237 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
