Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

openssl_encrypt versions before 1.4.9 contain a shell injection vulnerability in the info command's reconstructed CLI block that interpolates untrusted metadata fields without quoting. Attackers can craft metadata values like pepper_name containing shell commands that execute when users copy the printed CLI block into a shell.
