{"cve":"CVE-2026-2611","nvd":{"published":"2026-05-19T10:16:22.983","modified":"2026-10-14T20:10:00.190","status":"Modified","description":"In MLflow version 3.9.0, the MLflow Assistant feature introduced improper origin validation in its /ajax-api endpoints. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":9.6},"cwes":["CWE-346","CWE-940"],"references":["https://github.com/mlflow/mlflow/commit/8f9c8a53af90842944101eb8b7d60706822c81bc","https://huntr.com/bounties/8462addd-b464-4a84-b6a2-5529604e6e5a","https://access.redhat.com/security/cve/CVE-2026-2611","https://bugzilla.redhat.com/show_bug.cgi?id=2479797","https://huntr.com/bounties/8462addd-b464-4a84-b6a2-5529604e6e5a"],"products":["lfprojects:mlflow"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-2611","score":0.00384,"percentile":0.32148,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-67c5-x5mf-rppq","url":"https://osv.dev/vulnerability/GHSA-67c5-x5mf-rppq","summary":"MLflow: Improper Origin Validation in MLflow Assistant /ajax-api Endpoints Enables Browser-Mediated Local Command Execution","modified":"2026-10-05T21:45:03.626608223Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":[">=3.9.0 <3.10.0"],"fixed":["3.10.0"]}]},{"id":"PYSEC-2026-418","url":"https://osv.dev/vulnerability/PYSEC-2026-418","summary":"MLflow: Improper Origin Validation in MLflow Assistant /ajax-api Endpoints Enables Browser-Mediated Local Command Execution","modified":"2026-07-01T20:22:58.289747Z","packages":[{"ecosystem":"PyPI","name":"mlflow","purl":"pkg:pypi/mlflow","ranges":[">=3.9.0 <3.10.0"],"fixed":["3.10.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
