{"id":"BIT-mlflow-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":["CVE-2026-2614","GHSA-42h5-h8qh-vv9v","PYSEC-2026-2654"],"modified":"2026-09-08T08:48:13.677180769Z","published":"2026-05-28T08:50:49.461Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"FIX","url":"https://github.com/mlflow/mlflow/commit/6e801f4259d96804c73107315b24cef0f6aa115a"},{"type":"ADVISORY","url":"https://huntr.com/bounties/19380271-3fbf-4beb-987e-6fd7069c55e6"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-2614"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:34456"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-2614"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2469309"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-2614.json"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:37275"},{"type":"WEB","url":"https://access.redhat.com/errata/RHSA-2026:60520"}],"affected":[{"package":{"name":"mlflow","ecosystem":"Bitnami","purl":"pkg:bitnami/mlflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.10.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mlflow/BIT-mlflow-2026-2614.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
