PYSEC-2026-2659 MLflow: Any authenticated user can enumerate all gateway secrets, endpoints, and model definitions

MLflow 3.9.0 with basic-auth --app-name basic-auth fails to enforce authorization checks for multiple Gateway API 'list' endpoints. Specifically, the BEFOREREQUESTHANDLERS dictionary in mlflow/server/auth/init.py does not include entries for ListGatewaySecretInfos, ListGatewayEndpoints, and...

PYSEC-2026-2655 MLFlow Creates a Temporary File With Insecure Permissions

In mlflow/mlflow versions prior to 3.11.0, the getorcreatenfstmpdir function in mlflow/utils/fileutils.py creates temporary directories with world-writable permissions 0o777, and the createmodeldownloadingtmpdir function in mlflow/pyfunc/init.py creates directories with group-writable permissions...

PYSEC-2026-2654 MLflow allows an unauthenticated remote attacker to read arbitrary files from the server's filesystem

A vulnerability in the createmodelversion handler of mlflow/server/handlers.py in mlflow/mlflow versions 3.9.0 and earlier allows an unauthenticated remote attacker to read arbitrary files from the server's filesystem. The issue arises when a CreateModelVersion request includes the tag...

PYSEC-2026-2657 MLFlow allows Tracing + Assessments Access

In the latest version of mlflow/mlflow, when the basic-auth app is enabled, tracing and assessment endpoints are not protected by permission validators. This allows any authenticated user, including those with NOPERMISSIONS on the experiment, to read trace information and create assessments for...

PYSEC-2026-2656 Arbitrary file write via tar traversal in mlflow

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 extractio...

PYSEC-2026-2661 MLflow has a command injection in mlflow/sagemaker/__init__.py

A command injection vulnerability exists in mlflow/mlflow versions before v3.7.0, specifically in the mlflow/sagemaker/init.py file at lines 161-167. The vulnerability arises from the direct interpolation of user-supplied container image names into shell commands without proper sanitization, whic...

PYSEC-2026-2658 MLflow Tracking Server Artifact Handler Directory Traversal Remote Code Execution Vulnerability

MLflow Tracking Server Artifact Handler Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of MLflow Tracking Server. Authentication is not required to exploit this vulnerability. The specific fla...

CVE-2026-8147

A flaw was found in MLflow. When authentication is enabled, any authenticated user can bypass experiment-level authorization controls on trace API endpoints. This is due to missing authorization validators, allowing unauthorized reading, deleting, and modifying of traces. This vulnerability can...

PYSEC-2026-1639 mlflow Creates of Temporary File in Directory with Insecure Permissions

In mlflow version 2.20.3, the temporary directory used for creating Python virtual environments is assigned insecure world-writable permissions 0o777. This vulnerability allows an attacker with write access to the /tmp directory to exploit a race condition and overwrite .py files in the virtual...

PYSEC-2026-1640 MLflow Tracking Server Model Creation Directory Traversal Remote Code Execution Vulnerability

MLflow Tracking Server Model Creation Directory Traversal Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of MLflow Tracking Server. Authentication is not required to exploit this vulnerability. The specific flaw...

PYSEC-2026-1642 MLflow Weak Password Requirements Authentication Bypass Vulnerability

MLflow Weak Password Requirements Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of MLflow. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of passwords...

PYSEC-2026-1637 MLflow Uncontrolled Resource Consumption vulnerability

In mlflow/mlflow version 2.17.2, the /graphql endpoint is vulnerable to a denial of service attack. An attacker can create large batches of queries that repeatedly request all runs from a given experiment. This can tie up all the workers allocated by MLFlow, rendering the application unable to...

PYSEC-2026-1646 MLflow Cross-Site Request Forgery (CSRF) vulnerability

A Cross-Site Request Forgery CSRF vulnerability exists in the Signup feature of mlflow/mlflow versions 2.17.0 to 2.20.1. This vulnerability allows an attacker to create a new account, which may be used to perform unauthorized actions on behalf of the malicious user...

PYSEC-2026-1638 MLflow has a Local File Read/Path Traversal in dbfs

A path traversal vulnerability exists in mlflow/mlflow version 2.15.1. When users configure and use the dbfs service, concatenating the URL directly into the file protocol results in an arbitrary file read vulnerability. This issue occurs because only the path part of the URL is checked, while...

PYSEC-2026-1658 MLflow Uncontrolled Resource Consumption vulnerability

In mlflow/mlflow version v2.13.2, a vulnerability exists that allows the creation or renaming of an experiment with a large number of integers in its name due to the lack of a limit on the experiment name. This can cause the MLflow UI panel to become unresponsive, leading to a potential denial of...

PYSEC-2026-1657 MLFlow improper input validation

Remote Code Execution can occur in versions of the MLflow platform running version 1.11.0 or newer, enabling a maliciously crafted MLproject to execute arbitrary code on an end user’s system when run due to unfiltered input...

PYSEC-2026-1660 MLFlow unsafe deserialization

Deserialization of untrusted data can occur in versions of the MLflow platform running version 0.5.0 or newer, enabling a maliciously uploaded PyTorch model to run arbitrary code on an end user’s system when interacted with...

PYSEC-2026-1645 Undefined Behavior in mlflow

A vulnerability in mlflow/mlflow version 2.11.1 allows attackers to create multiple models with the same name by exploiting URL encoding. This flaw can lead to Denial of Service DoS as an authenticated user might not be able to use the intended model, as it will open a different model each time...

PYSEC-2026-1654 MLFlow unsafe deserialization

Deserialization of untrusted data can occur in versions of the MLflow platform running version 2.0.0rc0 or newer, enabling a maliciously uploaded Tensorflow model to run arbitrary code on an end user’s system when interacted with...
