Prior to 0.11.1, vllm has a critical remote code execution vector in a config class named Nemotron_Nano_VL_Config. When vllm loads a model config that contains an auto_map entry, the config class resolves that mapping with get_class_from_dynamic_module(...) and immediately instantiates the returned class. This fetches and executes Python from the remote repository referenced in the auto_map string. Crucially, this happens even when the caller explicitly sets trust_remote_code=False in vllm.transformers_utils.config.get_config. In practice, an attacker can publish a benign-looking frontend repo whose config.json points via auto_map to a separate malicious backend repo; loading the frontend will silently run the backend’s code on the victim host. This vulnerability is fixed in 0.11.1.","published_at":"2025-12-01T22:45:42.566000Z","last_modified_at":null,"cvss_v3_score":7.1,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-94"],"nvd_references":["https://github.com/vllm-project/vllm/security/advisories/GHSA-8fr4-5q9j-m8gm","https://github.com/vllm-project/vllm/pull/28126","https://github.com/vllm-project/vllm/commit/ffb08379d8870a1a81ba82b72797f196838d0c86"],"vuln_status":null,"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":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:28:14.089317Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"H","value_label":"High"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"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":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"vllm-project","vendor_name":"vllm-project","product_slug":"vllm","product_name":"vllm","version_start":"< 0.11.1","version_start_inclusive":true,"version_end":"< 0.11.1","version_end_inclusive":true,"cpe23_uri":"cve5:vllm-project:vllm:< 0.11.1:< 0.11.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/vllm-project/vllm/security/advisories/GHSA-8fr4-5q9j-m8gm","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/vllm-project/vllm/pull/28126","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/vllm-project/vllm/commit/ffb08379d8870a1a81ba82b72797f196838d0c86","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2025-12-01T22:45:42.566000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:49:06.072201Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:49:06.072201Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:49:06.072201Z","label":"CVSS score revised","source":"cvelistv5"}]}
