A vulnerability was discovered in the Keybase Client for Windows before version 5.6.0 when a user executed the “keybase git lfs-config” command on the command-line. In versions prior to 5.6.0, a malicious actor with write access to a user's Git repository could leverage this vulnerability to potentially execute arbitrary Windows commands on a user's local system.
