This vulnerability allows a remote attacker to exploit cross-origin requests from a malicious webpage to interact with the MLflow Assistant running on a victim's local machine. By bypassing the loopback-only restriction, the attacker can modify the Assistant's configuration to enable full access, which in turn allows the execution of arbitrary commands via the Claude Code sub-agent. This issue is resolved in version 3.10.0.","published_at":"2026-05-19T09:16:42.745000Z","last_modified_at":"2026-07-15T02:19:31.990000Z","cvss_v3_score":9.6,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"poc","ssvc_automatable":false,"ssvc_technical_impact":"total","cwes":["CWE-346","CWE-940"],"nvd_references":["https://huntr.com/bounties/8462addd-b464-4a84-b6a2-5529604e6e5a","https://github.com/mlflow/mlflow/commit/8f9c8a53af90842944101eb8b7d60706822c81bc"],"vuln_status":"Modified","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":"2026-07-15T16:30:08.798535Z"},"effective_severity":"CRITICAL","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":"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":"C","value_label":"Changed"},{"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":"lfprojects","vendor_name":"lfprojects","product_slug":"mlflow","product_name":"MLflow","version_start":"3.9.0","version_start_inclusive":true,"version_end":"3.10.0","version_end_inclusive":false,"cpe23_uri":"cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*"},{"vendor_slug":"mlflow","vendor_name":"mlflow","product_slug":"mlflow-mlflow","product_name":"mlflow/mlflow","version_start":"unspecified","version_start_inclusive":true,"version_end":"3.10.0","version_end_inclusive":false,"cpe23_uri":"cve5:mlflow:mlflow-mlflow:unspecified:3.10.0"}],"exploit_refs":[],"news":[],"references":[{"url":"https://huntr.com/bounties/8462addd-b464-4a84-b6a2-5529604e6e5a","source_type":"MISC","tags":[]},{"url":"https://github.com/mlflow/mlflow/commit/8f9c8a53af90842944101eb8b7d60706822c81bc","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-05-19T09:16:42.745000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:44.167107Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:44.167107Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:44.167107Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T23:46:59.033383Z","label":"SSVC decision revised","source":"vulnrichment"}]}
