DELTA vulnerability datasets

This repository contains the three benchmark splits used by DELTA: Differential Evidence for LLM Taxonomy-Aware Software Vulnerability Detection.

Configurations

config	task	training knowledge base	validation/test
`primevul`	single-language	C/C++	C/C++
`megavul`	cross-language	C/C++	Java
`crossvul`	multi-language transfer	C, Go, Java, PHP, TypeScript	C++, C#, JavaScript, Python, Ruby, Rust, Scala

Each config has train, val and test splits. The training split is the knowledge-base construction set. In DELTA, each pair contributes two classification items during evaluation: the vulnerable version (label 1) and the fixed version (label 0).

Loading

from datasets import load_dataset

primevul = load_dataset("codemetic/DELTA", "primevul", split="train")
megavul_java = load_dataset("codemetic/DELTA", "megavul", split="test")
crossvul = load_dataset("codemetic/DELTA", "crossvul", split="val")

Or use the DELTA code directly:

python -m delta.cli run --config configs/primevul.yaml --run-id primevul-full

The loader pulls the data from this repository by default (data.source: hf).

Columns

The parquet files preserve the original benchmark columns, including:

vul_code, fixed_code
cwe or cwe_id, and cwe_description where available
language for CrossVul
project/CVE metadata for PrimeVul and MegaVul

Citation

Please cite the DELTA paper. See the project repository for the full author list and bibliography.

Notes

These datasets are redistributed for research convenience. Please also follow the terms of the original PrimeVul, MegaVul and CrossVul releases.
