Parallels Desktop Flaw Lets Unprivileged Mac Users Gain Root Access
JFrog's 'ParaShells' research details CVE-2026-90894, a Parallels Desktop local privilege escalation letting unprivileged macOS users gain root via tar argument injection.
JFrog researcher Yuval Moravchick disclosed CVE-2026-90894 ('ParaShells'), a critical local privilege escalation flaw demonstrated against Parallels Desktop 26.4.0 build 57513 on Apple silicon. The world-writable /var/run/prl_disp_service.socket accepts connections from unsigned clients, and argument injection into a tar extraction command via the --use-compress-program option executes attacker-controlled code with root privileges. The attack needs no administrator permissions, running VM, or Parallels-signed client, and a one-line PoC yielded a root shell. Risk is highest on developer workstations, shared training systems, and enterprise Macs.
