💡Find unauthorized document retrieval in your RAG app before it becomes a data-leak incident.

⚡ 30-Second TL;DR

What Changed

Checks whether a RAG system retrieves documents outside a user's permissions.

Why It Matters

Unauthorized retrieval is a major security risk for enterprise RAG deployments, where incorrect filtering can expose confidential data through model responses. This tool could help teams add access-control regression tests before production rollout.

What To Do Next

Clone the rag-access-check repository and run it against a staging RAG endpoint with synthetic documents and multiple user credentials.

Who should care:Developers & AI Engineers

Key Points

•Checks whether a RAG system retrieves documents outside a user's permissions.
•Supports both offline test cases and live HTTP API testing.
•Works with bearer-token and API-key authentication.
•The creator is seeking engineers to test it in non-sensitive environments.

🔑 Enhanced Key Takeaways

•The tool addresses the 'Sensitive Information Disclosure' risk, which is currently ranked as the #2 threat in the OWASP Top 10 for LLM applications.
•It targets the failure of basic metadata-filtering, which often fails to replicate complex Access Control Lists (ACLs) from enterprise SaaS platforms like Salesforce or Notion.
•The project aligns with the industry-wide shift toward open-source security tooling to combat data exfiltration, as proprietary vendor dashboards struggle to keep pace with evolving injection techniques.
•It functions as a 'Security RAG' utility by validating that dynamic permission filters are correctly applied during the retrieval stage rather than just at the ingestion layer.
•The tool is designed to mitigate the 'blast radius' of permissive AI agents, a critical concern given that 65% of data breaches in 2026 involve internal actors.

🛠️ Technical Deep Dive

Implements dynamic permission filtering validation during the retrieval phase of the RAG pipeline.
Supports integration with vector database clients to verify that query-time filters correctly map to user-specific ACLs.
Utilizes bearer-token and API-key injection to simulate authenticated sessions for cross-user document leakage testing.
Designed to test 'actually-reachable' code paths in RAG frameworks like LangChain and LlamaIndex.

🔮 Future ImplicationsAI analysis grounded in cited sources

Automated access control testing will become a mandatory CI/CD step for enterprise RAG deployments by 2027.

The high frequency of internal data breaches via RAG agents is forcing security teams to treat retrieval permissions as a critical compliance requirement.

Metadata-based filtering will be largely replaced by native identity-aware retrieval engines.

Current limitations in mirroring complex SaaS ACLs are driving a shift toward architectures that enforce permissions at the vector database query level.
