CVE-2026-0236

Security-control bypass via unrestricted Apple Events

Published May 13, 2026 · Updated May 13, 2026

Code injection in Palo Alto Networks Prisma Browser before 146.16.6.165 allows local users to issue unauthorized Apple Events on macOS. The AppleScript interface exposes an Apple Event handler without restricting which locally authenticated accounts can invoke browser commands. A non-admin account can use that handler to send commands outside its intended authority, bypassing browser security controls without user interaction.
