It achieves the following results on the evaluation set:

Loss: 0.5058
Accuracy: 0.8269

Model description

It is a classification model and is aimed to assist in classifying vulnerabilities by severity based on their descriptions.

How to get started with the model

>>> from transformers import AutoModelForSequenceClassification, AutoTokenizer
... import torch
...
... labels = ["low", "medium", "high", "critical"]
...
... model_name = "CIRCL/vulnerability-severity-classification-distilbert-base-uncased"
... tokenizer = AutoTokenizer.from_pretrained(model_name)
... model = AutoModelForSequenceClassification.from_pretrained(model_name)
... model.eval()
...
... test_description = "SAP NetWeaver Visual Composer Metadata Uploader is not protected with a proper authorization, allowing unauthenticated agent to upload potentially malicious executable binaries \
that could severely harm the host system. This could significantly affect the confidentiality, integrity, and availability of the targeted system."
... inputs = tokenizer(test_description, return_tensors="pt", truncation=True, padding=True)
...
... # Run inference
... with torch.no_grad():
...     outputs = model(**inputs)
...     predictions = torch.nn.functional.softmax(outputs.logits, dim=-1)
...
... # Print results
... print("Predictions:", predictions)
... predicted_class = torch.argmax(predictions, dim=-1).item()
... print("Predicted severity:", labels[predicted_class])
...
Predictions: tensor([[4.9335e-04, 3.4782e-02, 2.6257e-01, 7.0215e-01]])
Predicted severity: critical
