# 00 Vulnerability Index

This document provides the master index for the OWASP Top 10 for LLM Applications (2025) vulnerabilities.
Each entry includes its identifier, title, and primary category.

## Vulnerability catalog

| ID | Title | Category |
|---|---|---|
| LLM01:2025 | Prompt Injection | Input Integrity |
| LLM02:2025 | Sensitive Information Disclosure | Data Protection |
| LLM03:2025 | Supply Chain | Supply Chain |
| LLM04:2025 | Data and Model Poisoning | Data Integrity |
| LLM05:2025 | Improper Output Handling | Output Safety |
| LLM06:2025 | Excessive Agency | Access Control |
| LLM07:2025 | System Prompt Leakage | Configuration Security |
| LLM08:2025 | Vector and Embedding Weaknesses | Data Integrity |
| LLM09:2025 | Misinformation | Output Reliability |
| LLM10:2025 | Unbounded Consumption | Resource Management |

## Cross-reference matrix

Each vulnerability document follows a consistent structure:

1. Description — what the vulnerability is and how it manifests in LLM systems.
2. Risk — concrete consequences of exploitation and business impact.
3. Vulnerability checklist — indicators that the system is exposed.
4. Prevention controls — defensive measures and rectification steps.
5. Example attack scenarios — realistic exploitation narratives.
6. Detection guidance — signals and methods to identify exposure.
7. Remediation — immediate and long-term actions to contain and resolve.
