Does this matter?

Lower severity and a low EPSS score (0.23%). Track it; it rarely justifies an emergency change on its own.

Description

HackerOne community member Dao Hoang Anh (yoyomiski) has reported an improper neutralization of whitespace in the username when adding new users. A username with leading or trailing whitespace could be virtually indistinguishable from its legitimate counterpart when the username is displayed in the UI, potentially leading to confusion.
