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.","published_at":"2026-07-01T16:53:32.326000Z","last_modified_at":"2026-07-02T17:55:37.087000Z","cvss_v3_score":5.5,"cvss_v3_vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":false,"ssvc_technical_impact":"partial","cwes":["CWE-73"],"nvd_references":["https://huntr.com/bounties/1875d257-5b03-4a69-ac70-e98653fa12c7","https://github.com/keras-team/keras/commit/d5a88bdb137c0d3039b8f4bbbe8c7099925cc10c"],"vuln_status":"Awaiting Analysis","trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-07-01T18:23:34.992991Z","updated_at":"2026-07-04T01:43:39.485079Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.0","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"R","value_label":"Required"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"keras-team","vendor_name":"keras-team","product_slug":"keras-team-keras","product_name":"keras-team/keras","version_start":"unspecified","version_start_inclusive":true,"version_end":"3.12.2, 3.14.1","version_end_inclusive":false,"cpe23_uri":"cve5:keras-team:keras-team-keras:unspecified:3.12.2, 3.14.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://huntr.com/bounties/1875d257-5b03-4a69-ac70-e98653fa12c7","source_type":"MISC","tags":[]},{"url":"https://github.com/keras-team/keras/commit/d5a88bdb137c0d3039b8f4bbbe8c7099925cc10c","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-07-01T16:53:32.326000Z","label":"CVE published","source":null}]}
