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.","published":"2026-05-11T19:02:46.025Z","modified":"2026-08-07T11:49:13.876608144Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.00712,"percentile":0.50175,"asOf":"2026-08-08"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"mlflow","fixedVersion":"3.10.0"}],"fix":{"url":"https://github.com/mlflow/mlflow/commit/6e801f4259d96804c73107315b24cef0f6aa115a","label":"mlflow/mlflow@6e801f4"},"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:49:13.876608144Z"}}
