MLflow disclosed a high-severity vulnerability, tracked as CVE-2026-69148 and GHSA-gqch-g4w5-7qcw, in which the CreateModelVersion API's source validation fails to check READ permission on a referenced run_id1. An authenticated user can reference another user's run_id to create a model version whose artifact URI points at the victim's artifact directory, then read arbitrary files via GET /model-versions/get-artifact, bypassing experiment-level READ permission gates. Versions below 3.15.0 are affected; version 3.15.0 patches the issue.
