Summary

Keras versions up to and including 3.13.2 are vulnerable to an arbitrary HDF5 file read due to an incomplete fix for CVE-2026-1669. The vulnerability resides in the `H5IOStore._verify_dataset()` and `file_editor.py` methods, which fail to check the `dataset.is_virtual` property of HDF5 datasets.

This allows an attacker to craft a malicious `.keras` model archive or `.h5` weights file containing a Virtual Dataset (VDS) that references external HDF5 files on the victim's filesystem.

When the victim loads the model using `keras.models.load_model()` or `keras.saving.load_model()`, the external file is transparently read, leading to potential information disclosure. Fixed in versions 3.12.2 and 3.14.1.

A flaw was found in Keras. This vulnerability leads to information disclosure, allowing an attacker to access sensitive data from the victim's filesystem.

Moderate: This information disclosure flaw in Keras affects Red Hat OpenShift AI components that utilize Keras. Exploitation requires user interaction, specifically loading an untrusted model, which limits the attack vector to scenarios where users process external, potentially malicious, model files.

Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N). Weakness: CWE-22.

Affected Red Hat products: Red Hat OpenShift AI (RHOAI). Red Hat does not currently list a fixing RHSA for this CVE.

Is CVE-2026-12480 exploited?

No exploitation is reported in the sources VulniPulse tracks: CVE-2026-12480 is not in the CISA KEV catalog (checked ) and this advisory does not report exploitation. That is not proof the vulnerability cannot be exploited.
