A path traversal vulnerability exists in the _create_model_version() function within server/handlers.py of the mlflow/mlflow repository, due to improper validation of the source parameter. Attackers can exploit this vulnerability by crafting a source parameter that bypasses the _validate_non_local_source_contains_relative_paths(source) function's checks, allowing for arbitrary file read access on the server. The issue arises from the handling of unquoted URL characters and the subsequent misuse of the original source value for model version creation, leading to the exposure of sensitive files when interacting with the /model-versions/get-artifact handler.
CVE-2024-1558
This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 0.9%, top 45% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
