CVE-2026-10766Public exploit

Dataset corruption via schema-blind DataFrame hashing

Published Jun 3, 2026 · Updated Jun 3, 2026

Weak DataFrame hashing in Iguazio MLRun 1.12.0-rc1 through 1.12.0-rc3 allows local users to corrupt dataset artifacts. calculate_dataframe_hash hashes normalized pandas values without schema or dtype metadata, so distinct DataFrames can receive the same hash-derived path. Authenticated users with artifact write access must supply colliding DataFrames, causing silent overwrite, stale reads, or incorrect metadata.
