High impact if exploited, but EPSS currently rates exploitation as unlikely (0.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

A privilege escalation vulnerability exists in the virtual machine archive restoration functionality of Parallels Desktop for Mac version 20.1.1 (55740). When an archived virtual machine is restored, the prl_vmarchiver tool decompresses the file and writes the content back to its original location using root privileges. An attacker can exploit this process by using a hard link to write to an arbitrary file, potentially resulting in privilege escalation.
