+Subject: [PATCH] WebAPI: Trim leading whitespaces on Run External Program
+ fields
+
+Hacked qbt instances may contain malicious script placed in Run External Program and the script
+will attempt to hide itself by adding a lot whitespaces at the start of the command string.
+Users may mistake the field of being empty but is actually not.
+So trim the leading whitespaces to easily expose the malicious script.
+
+Note that GUI already trim the fields and only WebAPI doesn't trim them. This patch will unify
+the behavior.
