Open WebUI has Unauthorized File and Knowledge Base Content Access via RAG Vector Search

Unauthorized File and Knowledge Base Content Access via RAG Vector Search

Affected Component

RAG source resolution in chat completion pipeline:

backend/open_webui/retrieval/utils.py (lines 963-965, 1063-1068, 1126-1131 in get_sources_from_items)

Affected Versions

Current main branch (commit 6fdd19bf1) and likely all versions with RAG functionality.

Description

The get_sources_from_items function resolves file and knowledge base references into vector search queries during chat completion. Three of the five code paths perform vector store queries without any authorization check, allowing users to extract content from files and knowledge bases they do not have access to.

Path	Lines	Access Check
`type: "file"`, full-context	1044-1050	✅ `has_access_to_file`
`type: "file"`, non-full-context (default)	1063-1068	❌ None
`type: "collection"`	1070-1118	✅ Present
`type: "text"` with `collection_name`	963-965	❌ None
Bare `collection_name`/`collection_names`	1126-1131	❌ None

The three unprotected paths pass user-supplied collection names directly to query_collection(), which queries the vector store without any authorization. Collection names follow predictable formats: file-<file_id> for files and the knowledge base UUID for knowledge bases.
