A privilege escalation vulnerability exists in the Snapshot functionality of Parallels Desktop for Mac version 20.1.1 (build 55740). When a snapshot of a virtual machine is taken, a root service writes to a file owned by a normal user. By using a hard link, an attacker can write to an arbitrary file, potentially leading to privilege escalation.
