The issue applies to Apache Answer through 2.0.2 only when custom role configurations separate the question.unpin permission from the question.hide and question.show permissions. A user with question.unpin but without question.hide or question.show can perform hide or show operations.
The attacker must be an authenticated user who has been granted the question.unpin permission. The vulnerability does not state that users without this permission can exploit the issue.
The issue specifically describes custom role configurations that separate these permissions. The provided information does not establish whether the default role configuration separates them.
Upgrade Apache Answer to version 2.0.3, which fixes the permission check. Until upgrading, review roles granted question.unpin and remove that permission from users who should not be able to hide or restore questions.
