CVE-2026-121552 · Severity: medium · CVSS 4.3 · Published 2026-11-03

Dromara domain-admin is a domain and SSL certificate monitoring platform. An authenticated user can enumerate members of groups they do not belong to by requesting the POST /api/getGroupUserList endpoint with sequential group IDs, disclosing usernames, roles, and permissions. An attacker with any valid account can discover which users belong to other teams and their access levels within those teams.

## Technical details

The getGroupUserList API handler in group_user_api.py lacks authorization checks: it verifies authentication but does not validate that the requesting user belongs to the queried group before returning member details. An authenticated attacker can enumerate group_id values to retrieve group membership, leader flags, edit permissions, and owner usernames from any group in the system.
