LLM Document Chat Security Testing

AnythingLLM Security Testing: Default Credentials, API Key, Database, and .env JWT_SECRET

📅 July 3, 2026 ⏱ 11 min read 🏷 AnythingLLM, LLM Security, JWT_SECRET, Document Chat, Workspace Security, SQLite, LLM API Key Exposure, Prompt Injection

AnythingLLM is a widely deployed open-source LLM document chat platform used to upload and query organizational documents (PDFs, Word files, code, data) using AI — it stores all uploaded documents, their embeddings, and complete conversation history. Key security considerations: JWT_SECRET signs authentication tokens; the platform supports both single-user mode (password-only) and multi-user mode (user accounts); LLM provider API keys (OpenAI, Anthropic, Azure, Ollama) are stored in the system_settings SQLite table; and uploaded document content is stored in a vector store accessible via the API. Prompt injection against the workspace chat endpoint may expose system prompts or other documents in the knowledge base. This guide covers systematic AnythingLLM security assessment.

AnythingLLM Security Hardening Checklist:

Use multi-user mode for any deployment with multiple users — AnythingLLM's single-user mode uses only a password (no username) which provides minimal access control; migrate to multi-user mode for environments with multiple users to implement proper user account management and audit logging; in multi-user mode, implement role-based access control to restrict which workspaces each user can access; audit user accounts regularly and revoke access for departed team members; the single-user password is stored as a hash in system_settings — audit its strength and rotate regularly
Protect JWT_SECRET and LLM provider API keys — JWT_SECRET signs authentication tokens; protect it in environment variables and rotate immediately if compromised; LLM provider API keys (OpenAI, Anthropic, Azure, Cohere) are stored in the system_settings SQLite table in plaintext; these keys should be treated as high-value credentials since they provide direct access to paid LLM services; implement spending limits and usage alerts on all LLM provider accounts connected to AnythingLLM; store the SQLite database with 600 file permissions accessible only to the AnythingLLM process
Secure uploaded document storage and implement document classification — AnythingLLM stores all uploaded document content in JSON files on the filesystem and in vector embeddings in the SQLite database; documents uploaded to AnythingLLM represent confidential organizational knowledge; restrict filesystem access to the STORAGE_DIR to the AnythingLLM process user only; implement network-level access controls to prevent unauthorized access to the AnythingLLM instance; consider the sensitivity of all documents before uploading — all content becomes queryable via the workspace chat API
Implement prompt injection defenses for sensitive document workspaces — AnythingLLM workspace chat is vulnerable to prompt injection; users or external content that manipulates the chat can attempt to extract document content, system prompts, or other knowledge base information; implement workspace-level access controls to restrict which users can interact with sensitive document workspaces; add a system prompt instruction to avoid disclosing document content directly; monitor chat logs for prompt injection attempts; consider whether public-facing chatbots built on AnythingLLM should have access to all documents in a workspace or only curated content
Restrict network access and implement reverse proxy authentication — expose AnythingLLM only to authorized networks using a reverse proxy; implement additional authentication at the reverse proxy level for sensitive deployments; disable the AnythingLLM API endpoints for external access if only the UI is needed; implement rate limiting on the chat endpoint to prevent document extraction via repeated queries; monitor for unusual access patterns such as bulk document queries or chat history exports; implement network-level logging of all API access for audit purposes

Security Test	Method	Risk
LLM API key extraction from system_settings	SQLite SELECT from system_settings WHERE label LIKE '%ApiKey%' — all LLM provider API keys stored in plaintext (OpenAI, Anthropic, Azure OpenAI, Cohere, HuggingFace)	Critical
JWT_SECRET extraction and token forgery	Read .env JWT_SECRET — JWT signing key; forge valid tokens as any AnythingLLM user bypassing password authentication in multi-user mode	Critical
Workspace chat prompt injection	POST /api/v1/workspace/{slug}/chat — inject adversarial prompt to extract system prompt content, enumerate documents in knowledge base, or exfiltrate document snippets via LLM responses	High
Chat history enumeration	GET /api/v1/workspace/{slug}/chats — complete conversation history for all users in the workspace; may reveal sensitive business discussions, document queries, and organizational context	High
Document filesystem extraction	Read STORAGE_DIR/documents/ — all uploaded documents stored as JSON with extracted plaintext content; complete organizational knowledge base accessible without API-level access controls	High
