{"id":"CVE-2026-2614","summary":"Arbitrary File Read via Prompt Tag Source Validation Bypass in mlflow/mlflow","details":"A vulnerability in the `_create_model_version()` handler of `mlflow/server/handlers.py` in mlflow/mlflow versions 3.9.0 and earlier allows an unauthenticated remote attacker to read arbitrary files from the server's filesystem. The issue arises when a `CreateModelVersion` request includes the tag `mlflow.prompt.is_prompt`, which bypasses source path validation. This enables an attacker to store an arbitrary local filesystem path as the model version source. The `get_model_version_artifact_handler()` function later uses this source to serve files without verifying the model version's prompt status, leading to a complete confidentiality compromise. This issue is fixed in version 3.10.0.","aliases":["BIT-mlflow-2026-2614","GHSA-42h5-h8qh-vv9v","PYSEC-2026-2654"],"modified":"2026-07-16T03:31:04.614974841Z","published":"2026-05-11T19:02:46.025Z","database_specific":{"cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/2xxx/CVE-2026-2614.json","cna_assigner":"@huntr_ai"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/19380271-3fbf-4beb-987e-6fd7069c55e6"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-2614.json"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:34456"},{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2026:37275"},{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-2614"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/2xxx/CVE-2026-2614.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2614"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2469309"},{"type":"FIX","url":"https://github.com/mlflow/mlflow/commit/6e801f4259d96804c73107315b24cef0f6aa115a"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/mlflow/mlflow","events":[{"introduced":"0"},{"fixed":"d0b97413e383796f1ca742b20cac74543185816c"},{"fixed":"6e801f4259d96804c73107315b24cef0f6aa115a"}],"database_specific":{"cpe":"cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"3.10.0"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v3.10.0rc0","nightly","v3.0.0","v2.2.0","v1.7.0","1.0.0","v0.8.1","v0.8.0","v0.7","v0.6.0","v0.5.0","v0.4.2","v0.4.1","v0.4.0","v0.3.0","v0.2.1","v0.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-2614.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
