New technical report flags HDF5 files as security risk

A technical assessment of the NumPy ecosystem argues that safety, security and privacy reviews should treat HDF5 input as potentially dangerous rather than inert data. The report stresses that determining who supplies the authority to process a file matters as much as who parses the bytes, prompting discussion among information security practitioners about supply-chain and data-parsing risks.

Why now: The report challenges the common assumption that scientific data files are safe to parse, raising concern among NumPy and HDF5 users.
