CVE-2026-29071 Details
Description
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to version 0.8.6, any authenticated user can read other users' private memories via `/api/v1/retrieval/query/collection`. Version 0.8.6 patches the issue.
An insecure direct object reference vulnerability has been identified in Open WebUI versions prior to 0.8.6. This vulnerability allows any authenticated user to access private memories and files of other users, including administrators. The issue arises from a lack of proper authorization checks in the collection querying API, which enables users to exploit predictable collection name patterns to retrieve sensitive information.
The vulnerability can be addressed by adding ownership validation in the collection querying handler to ensure users can only access their own memories and files. Additionally, the user search API should be restricted to admin-only access or limited to non-privileged fields.
