CVE-2025-15036
CWE-29Published: March 30, 2026· Updated: Mar 30, 2026
Official Description
A path traversal vulnerability exists in the `extract_archive_to_dir` function within the `mlflow/pyfunc/dbconnect_artifact_cache.py` file of the mlflow/mlflow repository. This vulnerability, present in versions before v3.7.0, arises due to the lack of validation of tar member paths during extraction. An attacker with control over the tar.gz file can exploit this issue to overwrite arbitrary files or gain elevated privileges, potentially escaping the sandbox directory in multi-tenant or shared cluster environments.
Risk Analysis
This critical vulnerability is a path traversal flaw in MLflow's extract_archive_to_dir function, affecting versions before v3.7.0. The lack of validation for tar member paths during extraction allows an attacker to overwrite arbitrary files or gain elevated privileges. This could lead to sandbox escapes in multi-tenant or shared cluster environments, with a CVSS score of 9.6.
No public exploit is currently known for this vulnerability. It is remotely exploitable with low attack complexity, but requires user interaction.
Upgrade MLflow to version v3.7.0 or later to mitigate this path traversal vulnerability. Implement strict validation of archive contents and paths before extraction.
Technical Analysis
CVE-2025-15036 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation does not require any privileges, though user interaction (Required) is needed, which slightly reduces the risk of mass automated attacks.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.6.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
