Zowe CLI

BugFix: Censored sensitive connection properties from the diagnostic details serialized into workflow and job submission command errors. #2784
BugFix: Prevented the daemon client from connecting to a Windows named pipe that belongs to a different user. #2790
BugFix: Hardened daemon client authentication so that another local user cannot drive a daemon they do not own. The daemon now generates a random secret token at startup, stores it in the owner-only daemon_pid.json file, and requires every client request to echo it back (compared in constant time). Because only the owner can read that file, this closes a gap on Windows, where the named pipe can be opened by local users other than the owner and the previously self-asserted user name check was insufficient. #2743
BugFix: Fixed "Access is denied" error when running CLI commands on Windows if daemon mode is active. #2808

Imperative

BugFix: The Config.set function, ConfigProfiles.set function, and the ConfigSecure property walkers now reject dotted paths whose segments are empty or use reserved property names. #2807
BugFix: Escaped regular-expression metacharacters in secure values before masking them in the Censor.censorRawData function. #2799
BugFix: Redacted sensitive environment variables and command-line arguments from the diagnostic information written to the log when a command handler fails to load or throws an error. This prevents credentials supplied via environment variables (for example, ZOWE_OPT_PASSWORD) from being persisted to disk in plain text. #2788
BugFix: Fixed an issue where passing an object with null values to the Censor.mCensorObject function caused a runtime error. Now, only non-null values are recursively handled in this function. #2784
BugFix: Added an optional token property to the IDaemonResponse interface. The daemon client sends this secret token (read from the owner-only daemon PID file) so the daemon can authenticate the client as its owner. #2743
