An unauthenticated attacker could use this flaw to escape the shared directory and access the contents of directories outside the share.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.18%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
