Niefy wx-api through 0.8.2 contains an authentication bypass vulnerability that allows unauthenticated attackers to impersonate WeChat fans by supplying a raw openid cookie to fan-facing controllers. Attackers knowing a victim's openid can call /wxUser/getUserInfo and /wxUserTags endpoints to read nickname, phone, unionid and tags, and add or remove fan tags.
