Root privilege escalation via symlink-following ownership change
Published Jun 3, 2025 · Updated Jun 3, 2025
Incorrect ownership assignment in Parallels Desktop for Mac 20.1.1 (55740) allows local users to gain root privileges through snapshot deletion. The root-privileged prl_disp_service follows a user-controlled Snapshots directory symlink and recursively assigns ownership of the linked root-owned files to that user. A low-privileged macOS account with a virtual machine and snapshot can then modify or delete the reassigned files and influence root services.
