The Draper VDISC dataset is a source‑code vulnerability detection dataset containing 1.27 million functions mined from open‑source software, each annotated with potential vulnerabilities via static analysis. The data are split into training, validation, and test sets in an 80:10:10 ratio, stored in HDF5 format. Each function's source code is stored as a variable‑length UTF‑8 string and includes five binary vulnerability labels corresponding to four common CWEs (CWE‑120, CWE‑119, CWE‑469, CWE‑476) and an “other CWE”. The dataset is sponsored by the U.S. Air Force Research Laboratory as part of the DARPA MUSE program.
