fwupd information disclosure vulnerability

fwupd is a plugin that supports firmware updates for session software on Linux platforms. fwupd 1.8.5 previously contained an information disclosure vulnerability that stemmed from the fact that when creating an OPERATOR user account on BMC, the redfish plugin saved the automatically generated password to /etc/fwupd/redfish.conf without restriction, and an attacker can exploit the vulnerability to read the same configuration file.
