CVE-2026-44567 Details
Description
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.1.124, the API does not properly validate that the user has an authorized user role of user. By default, when Open WebUI is configured with new sign-ups enabled, the default user role is set to pending. In this configuration, an administrator is required to go into the Admin management panel following a new user registration and reconfigure the user to have a role of either user or admin before that user is able to access the web application. This vulnerability is fixed in 0.1.124.
A vulnerability exists in Open WebUI, an offline artificial intelligence platform, prior to version 0.1.124. The issue stems from the API's failure to properly validate user roles, specifically for accounts marked as 'pending'. When new sign-ups are enabled, users are assigned a 'pending' role by default, requiring administrative intervention to change their status before they can access the application. This vulnerability allows 'pending' users to make authenticated API calls as if they had a 'user' role, bypassing the intended authorization process.
Users are advised to update Open WebUI to version 0.1.124 or later, where this vulnerability has been fixed.
