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."}], "lastModified": "2026-05-27T18:57:06.770", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:lfprojects:mlflow:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "C8CA51FC-A1F9-4F91-B400-F7C9691394E0", "versionEndExcluding": "3.10.0"}], "operator": "OR"}]}], "sourceIdentifier": "security@huntr.dev"}
