On dev.sub.gargantext.org, I have made a configuration where the bug happens.

In a shared folder, create 2 teams:

• user1Only
• user2Only

When connected as user1, on plane navigation, click on the the folder to go up (which should be .. instead of the name of the folder btw). Then user can access to a team he should not be able to see: https://dl.gargantext.org/user1Only.png

In the vertical tree we do not have such issue since we can not go up from the team. From a team: user should not be able to go up.
