Introduction
Generative AI, led by Large Language Models (LLMs), has become the most disruptive force in digital transformation since the advent of the internet. Enterprises are embedding LLMs into search, customer service, software development, fraud detection, and countless other domains—often at breakneck speed to capture competitive advantage.
Yet, with these opportunities come new risks. GenAI systems do not just process data; they generate content, make decisions, and, in agentic architectures, even take autonomous actions. The “black box” nature, probabilistic behavior, and data-hungry training regimes of these models introduce a spectrum of security, privacy, and governance threats that are unfamiliar to traditional application security and DevSecOps teams.
Recognizing this gap, the OWASP GenAI Security Project set out to provide the clarity, structure, and actionable guidance needed for organizations to securely leverage GenAI. In this report, we dissect the project’s origins, technical approach, and the tangible impact it is having across industry and government.
The Genesis and Expansion of the OWASP GenAI Security Project
The Open Worldwide Application Security Project (OWASP) has long been synonymous with best practices in application security, most notably through its “Top 10” vulnerability lists that help organizations focus on the most critical risks. However, the arrival of LLMs and GenAI models rapidly exposed the inadequacy of existing frameworks in addressing the unique threats these systems present.
In response, OWASP launched the “Top 10 for LLM Applications,” a living document identifying the most pressing vulnerabilities in LLM-powered applications. The overwhelming industry demand for guidance, coupled with the fast-moving research landscape, catalyzed the project’s expansion. By early 2024, the initiative was elevated to the OWASP GenAI Security Project, now a flagship, globally recognized framework covering a comprehensive set of risks, countermeasures, and governance strategies for GenAI.

Technical Details and Core Functionality
Fundamental Structure
The OWASP GenAI Security Project is structured to address the full lifecycle of GenAI adoption:
- Development: Secure model training, fine-tuning, data pipeline protection, and adversarial robustness.
- Deployment: Integration of LLMs into production environments, with controls for prompt input, output handling, and model isolation.
- Operation: Monitoring, incident response, and continuous red teaming of deployed GenAI systems.
- Governance: Organizational controls, risk assessments, compliance mapping, and cross-functional accountability.
The framework is dynamic, updated frequently in response to new research, real-world incidents, and regulatory developments.
The LLM Top 10 Risks (2025)
The LLM Top 10 serves as the cornerstone of the project, identifying the most prevalent and high-impact vulnerabilities in GenAI applications. The 2025 edition reflects a thorough synthesis of incident data, academic research, and practitioner feedback, and introduces new categories specific to emerging technologies like RAG (Retrieval-Augmented Generation) and embedding vectors.
The Risks (2025 Snapshot):
- Prompt Injection: Manipulation of LLM behavior via crafted user/system prompts, leading to privilege escalation, data leakage, or unwanted actions.
- Sensitive Information Disclosure: LLMs inadvertently leaking confidential or regulated information in their outputs.
- Supply Chain Vulnerabilities: Risks from tampered pre-trained models, poisoned training data, or compromised datasets.
- Data and Model Poisoning: Injection of malicious data during model creation or tuning, subverting model behavior or embedding backdoors.
- Improper Output Handling: Failure to validate or sanitize LLM outputs, exposing systems to code injection, XSS, or other exploits.
- Excessive Agency: Granting too much autonomy to LLMs, especially in agentic/“self-acting” architectures, increasing risk of uncontrolled actions.
- System Prompt Leakage: Exposure of system-level prompts, allowing attackers to infer application logic or bypass controls.
- Vector and Embedding Weaknesses: Attacks against RAG and embedding-based systems, including malicious context injection or poisoning of vector databases.
- Misinformation: LLMs generating plausible but false, biased, or misleading content.
- Unbounded Consumption: Resource exhaustion attacks, leading to denial-of-service or runaway operational expenses.

Key Innovations and Differentiators
Risk Taxonomy Tailored for GenAI
Unlike traditional Top 10 lists, the OWASP GenAI taxonomy addresses risks that are novel and sometimes exclusive to LLMs and GenAI systems. For example, prompt injection and embedding poisoning have no true analogs in classic web or API security.
Security for Agentic and Autonomous Architectures
As GenAI systems become more autonomous—capable of acting as agents or orchestrating workflows—the attack surface expands considerably. OWASP’s guides provide in-depth mitigation strategies for risks unique to agentic AI, such as uncontrolled “chain-of-thought” attacks and privilege escalation via tool invocation.
Embedding and RAG Security
The 2025 update pioneers coverage of Retrieval-Augmented Generation and embedding-based systems, which are now central to grounding LLM outputs in enterprise data. The guidance addresses challenges like:
- Poisoning of vector stores
- Malicious context injection into RAG pipelines
- Data provenance and integrity for embeddings
Open, Community-Driven, and Global
OWASP’s open-source, collaborative approach ensures that its guidance remains current, practical, and globally relevant. The project’s large contributor base and rapid iteration cycle set it apart from slower-moving, proprietary frameworks.
Alignment with Legal, Compliance, and Ethical Standards
OWASP GenAI documentation bridges the gap between technical security controls and the legal, privacy, and ethical considerations increasingly required by regulators, customers, and the public.
