CVE-2026-69115: Missing Authorization in OpenIMSDK OpenIM Server (open-im-server)
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.
AI Analysis
Technical Summary
CVE-2026-69115 describes a missing authorization check in OpenIM Server v3.8.3. Authenticated users can bypass admin restrictions by submitting POST requests with regular user bearer tokens to endpoints /user/get_users, /user/get_all_users_uid, and /group/get_groups. The vulnerability arises from the absence of the authverify.CheckAdmin() call in the GetPaginationUsers, GetAllUserID, and GetGroups handlers, allowing unauthorized access to sensitive user and group data.
Potential Impact
An attacker with any authenticated user credentials can enumerate all platform users and groups, including private groups they are not part of. This exposure of user IDs, nicknames, manager level flags, group names, owner IDs, and member counts can lead to privacy violations and facilitate further targeted attacks or social engineering.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the affected API endpoints and monitor for unauthorized access attempts. Implement additional authorization checks to ensure only admin users can access these management APIs.
