kedro-datasets 9.3.0 through 9.6.0 Path Traversal via MatplotlibDataset Plot Name

Summary

kedro-datasets from 9.3.0 through 9.6.0 contains a path traversal vulnerability in MatplotlibDataset.save() that allows attackers to write files outside the dataset directory by supplying absolute plot names. Because validate_sub_path() strips leading slashes while pathlib's join discards the base path, attackers can create or overwrite files anywhere the process can write.

Evidence

Reported to the maintainer with a proof of concept that reproduced against the affected release.

Remediation

No fixed release is listed in the advisory. Check the references for upstream status.
