In pam/gkr-pam-module.c in GNOME Keyring before 3.27.2, the users password is kept in a session-child process spawned from the LightDM daemon. This can expose the credential in cleartext.
Weakness
The product transmits or stores authentication credentials, but it uses an insecure method that is susceptible to unauthorized interception and/or retrieval.
