CVE-2026-12480Public exploit

Local file disclosure via unchecked virtual datasets

Published Jul 1, 2026 · Updated Jul 1, 2026

Information disclosure in Keras before 3.12.2 and 3.13.0 through 3.14.0 allows local users to read process-accessible HDF5 files. KerasFileEditor reads HDF5 leaf datasets with value[()] without rejecting dataset.is_virtual, causing h5py to resolve attacker-supplied source mappings. Exploitation requires a victim to load an untrusted .keras or .h5 file, and disclosure is limited to HDF5 files readable by the Keras process.
