{"id":"CVE-2026-2611","summary":"Improper Origin Validation in mlflow/mlflow","details":"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.","aliases":["BIT-mlflow-2026-2611","GHSA-67c5-x5mf-rppq","PYSEC-2026-418"],"modified":"2026-07-16T03:31:12.367483494Z","published":"2026-05-19T09:16:42.745Z","database_specific":{"cna_assigner":"@huntr_ai","cwe_ids":["CWE-346"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/2xxx/CVE-2026-2611.json"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/8462addd-b464-4a84-b6a2-5529604e6e5a"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-2611.json"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-2611"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/2xxx/CVE-2026-2611.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2611"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2479797"},{"type":"FIX","url":"https://github.com/mlflow/mlflow/commit/8f9c8a53af90842944101eb8b7d60706822c81bc"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mlflow/mlflow","events":[{"introduced":"cf3d582a7b8a6f234e4d28ef6987bb8076c6ee54"},{"fixed":"d0b97413e383796f1ca742b20cac74543185816c"},{"fixed":"8f9c8a53af90842944101eb8b7d60706822c81bc"}],"database_specific":{"cpe":"cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"3.9.0"},{"fixed":"3.10.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-2611.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H"}]}
