⚡ Quick Summary
Published by the OWASP GenAI Security Project, OWASP GenAI Data Security: Risks and Mitigations 2026 (Version 1.0) provides a structured risk catalog and mitigation blueprint tailored to Large Language Models (LLMs), Generative AI, and Agentic AI applications. Evolving from the project's earlier data security guidance, this publication addresses the fundamental architectural challenge of modern AI: the context window merges disparate trust boundaries—such as system instructions, retrieved enterprise documents, and untrusted user inputs—into a flat namespace lacking native access controls. Across an enumerated taxonomy of 21 threat vectors (DSGAI01 through DSGAI21), the document establishes core data security posture management (AI-DSPM) principles, concrete attack paths, real-world CVE case studies, and actionable three-tier mitigations spanning foundational controls to advanced defense-in-depth engineering.
🧩 What's Covered
The publication structures generative AI data security around 13 operational AI-DSPM capabilities and a comprehensive 21-part risk catalog mapped across the full model and data lifecycle:
- Direct Exposure & Identity Risks (DSGAI01–DSGAI03): Sensitive data leakage across RAG and fine-tuning adapters, non-human identity (NHI) credential sprawl and OAuth scope inheritance in autonomous agents, and ungoverned shadow AI workflows.
- Pipeline & Ingestion Integrity (DSGAI04–DSGAI06): Multi-stage supply chain compromise, model artifact tampering (including stealthy DP-SGD removal), schema and snapshot path traversal failures (e.g., Qdrant CVE-2024-3584), and Model Context Protocol (MCP) tool poisoning or data drains.
- Governance & Regulatory Alignment (DSGAI07–DSGAI08): Data classification propagation across derived vectors, unlearning readiness, Data Protection Impact Assessments (DPIAs), and compliance obligations across GDPR Article 17, CCPA, and EU AI Act Article 10.
- Architectural & Runtime Vulnerabilities (DSGAI09–DSGAI17): Multimodal cross-channel leakage, synthetic data re-identification pitfalls, cross-session conversation bleed via shared KV caches, unsafe natural-language data gateways (text-to-SQL/Graph injection), vector database misconfigurations, excessive telemetry logging (e.g., Mixpanel incident), prompt over-sharing, endpoint assistant overreach, and RAG availability degradation.
- Model-as-Artifact Threats (DSGAI18–DSGAI21): Membership and embedding inversion, human-in-the-loop (HITL) annotation exposure, model exfiltration and knowledge distillation attacks, and retrieval-time disinformation poisoning.
Each risk profile provides technical mechanics, attacker capability tiers, illustrative enterprise scenarios, known exploits, and a crawl-walk-run mitigation matrix categorized by implementation responsibility (Buy, Build, or Both).
💡 Why it matters?
Traditional data security perimeters fail when applied to generative and agentic systems. When proprietary records are transformed into vector embeddings, ingested into inference contexts, or queried via autonomous agent tool chains, static access boundaries collapse. This guide gives governance, risk, and security teams a concrete technical baseline to audit AI architectures, enforce Data Bill of Materials (DBOM) tracking using CycloneDX ML-BOM standards, contain Non-Human Identity sprawl, and ensure verifiable erasure across both raw corpora and downstream derived artifacts.
❓ What's Missing
As the first part of a two-document release, this volume intentionally isolates risk identification and mitigation categorization from detailed, hands-on implementation workflows, which are deferred to a companion implementation guide. Additionally, emerging technical areas such as cryptographic unlearning and machine-to-machine agent attestation frameworks provide directional guidance rather than turnkey code architectures.
👥 Best For
AI security engineers, CISOs, data protection officers, AI governance leads, privacy engineers, and platform architects designing, securing, or auditing enterprise RAG pipelines, autonomous agentic workflows, and fine-tuning infrastructure.
