| # CVE Chat‑Style Multi‑Turn Cybersecurity Dataset (1999 – 2025) |
|
|
|   |
|
|
| ## 1. Project Overview |
|
|
| This repository hosts the **largest publicly available chat‑style, multi‑turn cybersecurity dataset to date**, containing **≈ 300 000 Common Vulnerabilities and Exposures (CVE) records** published between **1999 and 2025**. Each record has been meticulously parsed, enriched, and converted into a conversational format that is ideal for training and evaluating AI and AI‑Agent systems focused on vulnerability analysis, threat intelligence, and cyber‑defense automation. |
|
|
| ## 2. Key Highlights. Key Highlights |
|
|
| | Feature | Description | |
| | ------------------- | --------------------------------------------------------------------------------------- | |
| | Records | \~300 k CVE entries (1999‑2025) | |
| | Formats Covered | CVE 4.0 (legacy) & CVE 5.0+ (modern) | |
| | Parsing Accuracy | **100 %** (validated) | |
| | Enrichments | CVSS v2 & v3 metrics · CWE taxonomy · Affected‑product matrices · Expert system prompts | |
| | Conversation Depth | Multi‑turn (System / User / Assistant) | |
| | Processing Pipeline | Fully asynchronous, linearly scalable data‑engineering architecture | |
| | License | Apache license 2.0 | |
|
|
| ## 3. Intended Use Cases |
|
|
| - **Fine‑tuning LLMs** for vulnerability triage and severity prediction. |
| - **Temporal trend analysis** of vulnerability disclosures. |
| - **Retrieval‑Augmented Generation (RAG)** and autonomous **AI‑Agent** pipelines. |
| - **Real‑time threat‑intelligence** enrichment services. |
| - **Automated penetration‑testing** (pentest) orchestration. |
|
|
| > **Benchmark Note**\ |
| > Early experiments with *Llama 3.2* and *Gemma* models achieved **94 % accuracy** on CVE class‑prediction tasks after full fine‑tuning on this dataset. |
|
|
| ## 4. Dataset Structure |
|
|
| Each dialogue is stored as a single **JSON Lines (`.jsonl`)** object with **three top‑level keys**: |
|
|
| ```json |
| { |
| "System": "You are a cybersecurity expert specializing in penetration testing, vulnerability research, and exploit development. Provide comprehensive technical analysis of CVE vulnerabilities with academic rigor and practical exploitation insights.", |
| "User": "Provide a comprehensive technical analysis of CVE‑2010‑3763, including exploitation vectors, impact assessment, and remediation strategies.", |
| "Assistant": "## CVE‑2010‑3763 Vulnerability Details |
| |
| ### CVE Metadata |
| - **CVE ID**: CVE‑2010‑3763 |
| - **State**: PUBLISHED |
| ..." |
| } |
| ``` |
|
|
| ### Field Reference |
|
|
| | Key | Type | Description | |
| |-------------|--------|---------------------------------------------------------------------| |
| | `System` | string | System prompt that frames the assistant’s role and response style. | |
| | `User` | string | End‑user request or question. | |
| | `Assistant` | string | Model answer containing enriched CVE analysis and metadata. | |
|
|
| > **Note**: Multi‑turn conversations are represented as separate JSONL lines that share the same `System` context while `User` and `Assistant` evolve turn by turn. |
|
|
| ## 5. Processing Pipeline. Processing Pipeline |
|
|
| 1. **Source Aggregation** – CVE XML feeds (4.0) + JSON feeds (5.0+). |
| 2. **Asynchronous Parsing** – Custom Rust & Python pipeline (Tokio + asyncio) for 100 % parsing success. |
| 3. **Enrichment Layer** – CVSS scoring, CWE classification, product‑matrix generation. |
| 4. **Conversation Generation** – Expert prompts injected to produce System / User / Assistant structure. |
| 5. **Validation & QA** – Schema checks, de‑duplication, manual spot‑checks. |
|
|
|
|
|
|
| ## 6. Quick Start |
|
|
| ### Load with 🤗 `datasets` |
|
|
| ```python |
| from datasets import load_dataset |
| |
| cve_chat = load_dataset("<username>/<repo_name>", split="train") |
| print(cve_chat[0]) |
| ``` |
|
|
| ### Finetune Example (PEFT & QLoRA) |
|
|
| ```bash |
| python train.py \ |
| --model "meta-llama/Meta-Llama-3-8B" \ |
| --dataset "<username>/<repo_name>" \ |
| --peft lora \ |
| --bits 4 |
| ``` |
|
|
| ## 7. Data Splits |
