OpenObserve is a observability platform built specifically for logs, metrics, traces, analytics, designed to work at petabyte scale. A vulnerability has been identified in the "/api/{org_id}/users" endpoint. This vulnerability allows any authenticated regular user ('member') to add new users with elevated privileges, including the 'root' role, to an organization. This issue circumvents the intended security controls for role assignments. The vulnerability resides in the user creation process, where the payload does not validate the user roles. A regular user can manipulate the payload to assign root-level privileges. This vulnerability leads to Unauthorized Privilege Escalation and significantly compromises the application's role-based access control system. It allows unauthorized control over application resources and poses a risk to data security. All users, particularly those in administrative roles, are impacted. This issue has been addressed in release version 0.8.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
The vulnerability affects the '/api/{org_id}/users' endpoint, responsible for creating new users. The account creation process does not validate the correctness of the field specifying the user role in the transmitted payload. A regular, authenticated user can modify the HTTP request payload by specifying any role — including 'root' — and thus bypass the permission control mechanisms intended exclusively for administrators.
An attacker with access to a regular user account can escalate privileges to root level, gaining full control over the organization and its resources in the application. This poses a serious threat to data security and the integrity of the entire OpenObserve instance.
OpenObserve must be updated immediately to version 0.8.0 or later. The vendor informs that there are no known workarounds for this vulnerability.
