[MC-55592] The wildcard * fits into wrong commands without error.

For example I do this:

/scoreboard objectives add o dummy
Added new objective 'o' successfully

/scoreboard players set a o 1
Set score of o for player a to 1

/scoreboard players set b o 1
Set score of o for player b to 1

/scoreboard players set c o 1
Set score of o for player c to 1

/scoreboard teams add *
Added new team 'b' successfully
Added new team 'c' successfully
Added new team 'a' successfully

Clearly it makes no sense to put the wildcard as a team name, but it will create teams with the names of all the players in the scoreboard successfully. It also works in other "/scoreboard ..." commands in places where it shouldn't but I haven't tested all of them to give a complete list.
