{"id":"BIT-mlflow-2025-15031","summary":"Path Traversal Vulnerability in mlflow/mlflow","details":"A vulnerability in MLflow's pyfunc extraction process allows for arbitrary file writes due to improper handling of tar archive entries. Specifically, the use of `tarfile.extractall` without path validation enables crafted tar.gz files containing `..` or absolute paths to escape the intended extraction directory. This issue affects the latest version of MLflow and poses a high/critical risk in scenarios involving multi-tenant environments or ingestion of untrusted artifacts, as it can lead to arbitrary file overwrites and potential remote code execution.","aliases":["CVE-2025-15031","GHSA-fhff-qmm8-h2fp","PYSEC-2026-2656"],"modified":"2026-09-08T08:48:13.724606320Z","published":"2026-03-24T08:47:14.572Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://huntr.com/bounties/09856f77-f968-446f-a930-657d126efe4e"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-15031"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2025-15031"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2448912"},{"type":"WEB","url":"https://security.access.redhat.com/data/csaf/v2/vex/2025/cve-2025-15031.json"}],"affected":[{"package":{"name":"mlflow","ecosystem":"Bitnami","purl":"pkg:bitnami/mlflow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.11.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/mlflow/BIT-mlflow-2025-15031.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N"}]}],"schema_version":"1.9.0"}
