Impact
DisplayName allows all the characters from users, which leads to an XSS vulnerability when directly displayed in the issue list.
Patches
DisplayName is sanitized before being displayed. Users should upgrade to 0.12.9 or the latest 0.13.0+dev.
Workarounds
Check and update the existing users’ display names that contain malicious characters.
