## What is CVE-2026-69115?

CVE-2026-69115 is a high-severity missing authorization vulnerability in OpenIMSDK OpenIM Server (open-im-server), published on 11 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

OpenIM Server v3.8.3 contains a missing authorization vulnerability that allows any authenticated user to access admin-only management API endpoints by submitting POST requests with a regular user bearer token to /user/get_users, /user/get_all_users_uid, and /group/get_groups. Attackers can exploit the absent authverify.CheckAdmin() call in the GetPaginationUsers, GetAllUserID, and GetGroups handlers to enumerate all platform user accounts including userIDs, nicknames, and manager level flags, as well as all groups including private groups the user has never joined, exposing group names, owner IDs, and member counts.
