OWASP Adds RAG Security Cheat Sheet
A pull request merged into the OWASP/CheatSheetSeries repository on May 6, 2026, adds a new RAG security cheat sheet, according to the merged GitHub pull request. The change set totals +386 lines added and introduces 14 sections that span the RAG pipeline from document ingestion to output validation, per the PR. The contributor, Raza Sharif, wrote "RAG is now standard architecture for enterprise AI but introduces a unique attack surface..." and attached a companion training tool called DVRAG (Damn Vulnerable RAG Pipeline) that maps 25 vulnerabilities to the cheat-sheet sections, the PR notes. Each section contains practical Do/Don't guidance for practitioners. Editorial analysis: For practitioners, the addition provides a concise checklist-style reference to surface-level and pipeline risks specific to retrieval-augmented generation (RAG) deployments.
What happened
A pull request was merged into the OWASP/CheatSheetSeries repository on May 6, 2026, adding a new RAG security cheat sheet, per the merged GitHub pull request. The PR records +386 lines added and enumerates 14 sections covering the full RAG pipeline, from document ingestion through to output validation. The contributor, Raza Sharif, described the scope and rationale in the PR, writing "RAG is now standard architecture for enterprise AI but introduces a unique attack surface distinct from both traditional web vulnerabilities and standalone LLM risks." The PR also references a companion training tool, DVRAG (Damn Vulnerable RAG Pipeline), which the contributor says maps 25 vulnerabilities to the cheat-sheet sections.
Technical details
The PR lists 14 sections with practical Do/Don't guidance for each stage of a RAG system. The sections, as presented in the merged PR, cover:
- •Document Poisoning and Integrity
- •Embedding Security
- •Context Window Protection
- •Access Control Inheritance
- •Source Attribution and Verification
- •Chunk Isolation and Multi-Tenancy
- •Vector Index Integrity
- •Query Security
- •Output Validation
- •Tool and Agent Integration Safety
- •Response Caching Security
- •Pipeline Observability
- •Supply Chain and Connector Security
- •Fail-Closed Design
These are presented as actionable items and recommended controls in the PR's additions.
Industry context
Editorial analysis: Industry practitioners deploying retrieval-augmented generation (RAG) pipelines face a compound attack surface that crosses data ingestion, vector indexing, and LLM output layers. Centralized cheat sheets and hands-on training fixtures are commonly used in security teams to accelerate threat modeling and purple-team exercises. The inclusion of a deliberately insecure training artifact alongside prescriptive guidance follows established practice for applied security education and testing.
What to watch
Editorial analysis: Observers and practitioners can track adoption and community feedback on the repository to see which recommendations are refined or contested. Additional indicators to watch include contributions that add mitigations tied to specific vector-database implementations, connector hardening examples, or measurable test cases for the companion DVRAG tool in downstream security labs.
Scoring Rationale
A new OWASP cheat sheet is a practical resource for security and ML engineering teams working with RAG pipelines; pairing guidance with an insecure testbed increases its usefulness. The story is notable but not transformative for core model research.
