RAGFlow is an open-source RAG (Retrieval-Augmented Generation) engine based on deep document understanding. An authenticated user can exploit the Insecure Direct Object Reference (IDOR) vulnerability that may lead to unauthorized cross-tenant access (list tenant user accounts, add user account into other tenant). Unauthorized cross-tenant access: list user from other tenant (e.g., via GET /<tenant_id>/user/list), add user account to other tenant (POST /<tenant_id>/user). This issue has not yet been patched. Users are advised to reach out to the project maintainers to coordinate a fix.

The `add_llm` function in `llm_app.py` in infiniflow/ragflow version 0.11.0 contains a remote code execution (RCE) vulnerability. The function uses user-supplied input `req['llm_factory']` and `req['llm_name']` to dynamically instantiate classes from various model dictionaries. This approach allows an attacker to potentially execute arbitrary code due to the lack of comprehensive input validation or sanitization. An attacker could provide a malicious value for 'llm_factory' that, when used as an index to these model dictionaries, results in the execution of arbitrary code.
