HIGH 8.1EPSS 1.02%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (1.02%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

In yast2-printer up to and including version 4.0.2 the SMB printer settings don't escape characters in passwords properly. If a password with backticks or simliar characters is supplied this allows for executing code as root. This requires tricking root to enter such a password in yast.
