	# CVE → CWE Classifier (Qwen3-8B)

	A QLoRA fine-tune of Qwen3-8B that maps a free-text CVE description to the **CWE weakness
	ID(s)** it corresponds to. The LoRA adapter is merged into the base and released in 16-bit, so it
	loads directly with `transformers`. A higher-quality (larger) variant is at
	[`exploitintel/cve-cwe-qwen3-32b`](https://huggingface.co/exploitintel/cve-cwe-qwen3-32b).

	Trained only on labels where NVD and the CNA agree after roll-up to CWE View-1003 — see the
	[`cve-cwe-consensus`](https://huggingface.co/datasets/exploitintel/cve-cwe-consensus) dataset.

	## Results (held-out test split, 6,802 rows)

	\| Metric \| Score \|
	\|---\|---\|
	\| Exact-match \| 0.676 \|
	\| Micro-F1 \| 0.702 \|
	\| Macro-F1 \| 0.511 \|

	By difficulty (does the description name the weakness, or must it be inferred?):

	\| Stratum \| n \| Exact-match \| Micro-F1 \|
	\|---\|---\|---\|---\|
	\| Easy (weakness named) \| 2,046 \| 0.841 \| 0.870 \|
	\| Hard (must infer) \| 4,756 \| 0.605 \| 0.628 \|

	The macro-F1 reflects a dataset that caps majority CWEs (e.g. CWE-79) so rare weaknesses are
	learned rather than drowned out.

	Reading the numbers:
	- Macro-F1 is computed over the union of gold and predicted labels (125 = 117 gold + ~8 the model predicted outside the gold set). Those out-of-label predictions score ~0 and pull macro down, so 0.511 is a conservative figure.
	- Exact-match has an inherent ceiling of ~98.3%: ~1.74% of the test set (273 groups / 1,205 rows) are identical descriptions mapped to different CWEs (e.g. a bare "Windows Kernel Elevation of Privilege Vulnerability"), which a description-only model cannot disambiguate.
	- Scores are on the capped/balanced test split (~30% "easy" rows), so they are not directly comparable to metrics measured on a different (e.g. natural-distribution) split.

	## Usage

	```python
	import torch
	from transformers import AutoModelForCausalLM, AutoTokenizer

	mid = "exploitintel/cve-cwe-qwen3-8b"
	tok = AutoTokenizer.from_pretrained(mid)
	model = AutoModelForCausalLM.from_pretrained(mid, torch_dtype="auto", device_map="auto")

	messages = [
	{"role": "system", "content": "You are a vulnerability analyst. Given a CVE description, "
	"reply with only the CWE ID(s) it maps to, comma-separated."},
	{"role": "user", "content": "A SQL injection vulnerability in the login endpoint allows an "
	"unauthenticated attacker to execute arbitrary SQL via the username parameter."},
	]
	inputs = tok.apply_chat_template(messages, add_generation_prompt=True, return_tensors="pt").to(model.device)
	out = model.generate(inputs, max_new_tokens=32, do_sample=False)
	print(tok.decode(out[0][inputs.shape[-1]:], skip_special_tokens=True))
	# -> CWE-89
	```

	### GGUF / Ollama

	A `Q4_K_M` GGUF is included in this repo for local runners:

	```bash
	ollama run hf.co/exploitintel/cve-cwe-qwen3-8b:Q4_K_M
	```

	Set the same system prompt (`/set system You are a vulnerability analyst...`) so it returns bare CWE IDs.

	> Note: This Ollama command has not been verified end-to-end. This is a standard `qwen3`
	> model so the embedded template should apply normally — but if `ollama run` ignores the
	> system prompt and produces rambling text instead of a bare CWE ID, supply an explicit
	> ChatML Modelfile `TEMPLATE` as shown in the [Qwen3.5-4B card](https://huggingface.co/exploitintel/cve-cwe-qwen35-4b).

	## Training

	- Base: `Qwen/Qwen3-8B` (trained 4-bit via `unsloth/qwen3-8b-unsloth-bnb-4bit`)
	- Method: QLoRA (4-bit) with Unsloth, merged to 16-bit · released checkpoint: checkpoint-960 (final; eval loss declined monotonically through training)
	- Dataset: [`exploitintel/cve-cwe-consensus`](https://huggingface.co/datasets/exploitintel/cve-cwe-consensus) — 69,386 rows (55,810 / 6,774 / 6,802), majority CWEs capped at 2,500
	- Settings: 2 epochs · context 512 · LR 2e-4 · AdamW 8-bit · linear schedule · packing on · train-on-completions-only off · seed 3407
	- LoRA fine-tune, adapter merged into the base. Exact per-run LoRA rank/alpha, batch size, and weight decay were not logged to the repo.

	## Prompt format

	ChatML (Qwen3 standard). System prompt fixed; the description is the only user input — never feed the
	label or CVE-ID.

	- system: `You are a vulnerability analyst. Given a CVE description, reply with only the CWE ID(s) it maps to, comma-separated.`
	- user: the CVE description
	- assistant: `CWE-79, CWE-80`

	## Limitations

	- CWEs below the dataset's 50-example floor are not in the label space and won't be predicted.
	- Outputs CWE IDs as text and can occasionally emit a malformed/non-existent ID — validate against
	the official CWE list.
	- English-only; descriptions only (no code, CVSS, or references).
	- A triage/assist aid, not an authoritative CWE assignment — human-review before acting.
