1

Is it possible for a user (who might be in the same candidate group) to complete a task that’s has been assigned to another user (in the same group)?

2

Through the Java API’s yes, as there’s no check being done there on these things.

3

Experiencing otherwise. It is possible for this to happen through the REST API as we’re experiencing.
We’re using version 6.4.2.

4

And just to check, the user isn’t admin?

5

No. The user is not admin.

6

The REST API is similar to the Java API, as such it doesn’t do any extra checks vs the Java API.
