CallBackery versions before 0.62.0 for Perl leave a world-readable dump of the configuration database in /tmp when taking a configuration backup.
getConfigBlob() has the sqlite3 shell write the dump to /tmp/cbdump<pid> and never removes it. The file takes the process umask, and a symlink planted at that predictable name is followed.
The dump holds every user's password hash and every value saved by the application's forms. A local user can read these after any backup, and may redirect the dump to a file of their choosing.
