What is CVE-2026-119652?

HuLa-Server versions up to 3.0.7 expose an insecure direct object reference vulnerability in the FriendController.friendList method. This flaw enables authenticated users to exploit the uid parameter to gain access to the friend lists of other users. By sending GET requests to the /user/friend/page endpoint with a victim's uid, attackers can bypass the necessary checks intended for administrator or owner permissions, leading to unauthorized access to sensitive contact information of any user.

Affected Version(s)

HuLa-Server 0 <= 3.0.7
