CVE-2026-44560 Details
Description
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.9.0, the type: "file" (non-full-context), type: "text" with collection_name, and bare collection_name/collection_names paths in the get_sources_from_items function perform vector store queries without any authorization check, allowing users to extract content from files and knowledge bases they do not have access to. This vulnerability is fixed in 0.9.0.
A vulnerability in Open WebUI versions through 0.8.12 allows unauthorized access to file and knowledge base content via vector store queries. The issue arises in the 'get_sources_from_items' function, where certain query types bypass authorization checks, enabling users to access restricted information. This vulnerability affects the RAG source resolution in the chat completion pipeline.
Users can update to Open WebUI version 0.9.0 or later, where this vulnerability has been fixed.
