I have a Maven command with the parameter:
mvn test -Dcommon_password=!23foo
This command is being executed as
mvn test -Dcommon_password=dockerfoo
I.e. !23 is being substituted with docker.
Why does this happen and how can I avoid it?

This is history expansion: !23 is replaced with the 23rd command in your history.
To avoid this, use single quotes:
mvn test '-Dcommon_password=!23foo'

This is a password that can potentially contain all sorts of shell metacharacters. Properly quoting and escaping as in M. Kitt's answer is better than disabling just one of the possibilities that could occur. Of course, not having a password in process arguments in the first place would be better still. (-:

@JdeBP in my question I showed a password in a plain text just for simplicity reason. In a real project that argument takes the value from a Jenkins secret credential. So it’s masked and safe.
