CVE-2026-33865 (GCVE-0-2026-33865)

Vulnerability from nvd – Published: 2026-04-07 12:57 – Updated: 2026-04-14 15:13

Title

Stored XSS via unsafe YAML parsing in MLflow

Summary

MLflow is vulnerable to Stored Cross-Site Scripting (XSS) caused by unsafe parsing of YAML-based MLmodel artifacts in its web interface. An authenticated attacker can upload a malicious MLmodel file containing a payload that executes when another user views the artifact in the UI. This allows actions such as session hijacking or performing operations on behalf of the victim. This issue affects MLflow version through 3.10.1

Severity ?

5.1 (Medium)

In mlflow/mlflow, the FastAPI job endpoints under `/ajax-api/3.0/jobs/*` are not protected by authentication or authorization when the `basic-auth` app is enabled. This vulnerability affects the latest version of the repository. If job execution is enabled (`MLFLOW_SERVER_ENABLE_JOB_EXECUTION=true`) and any job function is allowlisted, any network client can submit, read, search, and cancel jobs without credentials, bypassing basic-auth entirely. This can lead to unauthenticated remote code execution if allowed jobs perform privileged actions such as shell execution or filesystem changes. Even if jobs are deemed safe, this still constitutes an authentication bypass, potentially resulting in job spam, denial of service (DoS), or data exposure in job results.

CVE-2026-0596 (GCVE-0-2026-0596)

Vulnerability from nvd – Published: 2026-03-31 14:25 – Updated: 2026-04-01 03:55

Title

Command Injection in mlflow/mlflow

Summary

A command injection vulnerability exists in mlflow/mlflow when serving a model with `enable_mlserver=True`. The `model_uri` is embedded directly into a shell command executed via `bash -c` without proper sanitization. If the `model_uri` contains shell metacharacters, such as `$()` or backticks, it allows for command substitution and execution of attacker-controlled commands. This vulnerability affects the latest version of mlflow/mlflow and can lead to privilege escalation if a higher-privileged service serves models from a directory writable by lower-privileged users.

Severity ?

9.6 (Critical)

CVE-2025-15031 (GCVE-0-2025-15031)

Vulnerability from nvd – Published: 2026-03-18 22:06 – Updated: 2026-03-19 13:52

Title

Path Traversal Vulnerability in mlflow/mlflow

Summary

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 extraction directory. This issue affects the latest version of MLflow and poses a high/critical risk in scenarios involving multi-tenant environments or ingestion of untrusted artifacts, as it can lead to arbitrary file overwrites and potential remote code execution.

Severity ?

8.1 (High)

CVE-2025-14287 (GCVE-0-2025-14287)

Vulnerability from nvd – Published: 2026-03-15 09:27 – Updated: 2026-03-17 12:44

Title

Command Injection in mlflow/mlflow

Summary

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, which are then executed using `os.system()`. This allows attackers to execute arbitrary commands by supplying malicious input through the `--container` parameter of the CLI. The issue affects environments where MLflow is used, including development setups, CI/CD pipelines, and cloud deployments.

Severity ?

7.5 (High)

Title

DNS Rebinding Vulnerability in mlflow/mlflow

Summary

MLFlow versions up to and including 3.4.0 are vulnerable to DNS rebinding attacks due to a lack of Origin header validation in the MLFlow REST server. This vulnerability allows malicious websites to bypass Same-Origin Policy protections and execute unauthorized calls against REST endpoints. An attacker can query, update, and delete experiments via the affected endpoints, leading to potential data exfiltration, destruction, or manipulation. The issue is resolved in version 3.5.0.

Severity ?

8.1 (High)

CVE-2025-0453 (GCVE-0-2025-0453)

Vulnerability from nvd – Published: 2025-03-20 10:11 – Updated: 2025-10-15 12:50

Title

Denial of Service through Batched Queries in GraphQL in mlflow/mlflow

Summary

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 respond to other requests. This vulnerability is due to uncontrolled resource consumption.

Severity ?

5.9 (Medium)

CVE-2024-8859 (GCVE-0-2024-8859)

Vulnerability from nvd – Published: 2025-03-20 10:09 – Updated: 2025-03-20 18:33

Title

Path Traversal in mlflow/mlflow

Summary

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 parts such as query and parameters are not handled. The vulnerability is triggered if the user has configured the dbfs service, and during usage, the service is mounted to a local directory.

Severity ?

7.5 (High)

CVE-2024-6838 (GCVE-0-2024-6838)

Vulnerability from nvd – Published: 2025-03-20 10:09 – Updated: 2025-03-20 14:25

Title

Uncontrolled Resource Consumption in mlflow/mlflow

Summary

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 service. Additionally, there is no character limit in the `artifact_location` parameter while creating the experiment.

Severity ?

5.3 (Medium)

CVE-2026-33865 (GCVE-0-2026-33865)

Vulnerability from cvelistv5 – Published: 2026-04-07 12:57 – Updated: 2026-04-14 15:13

Title

Stored XSS via unsafe YAML parsing in MLflow

Summary

MLflow is vulnerable to Stored Cross-Site Scripting (XSS) caused by unsafe parsing of YAML-based MLmodel artifacts in its web interface. An authenticated attacker can upload a malicious MLmodel file containing a payload that executes when another user views the artifact in the UI. This allows actions such as session hijacking or performing operations on behalf of the victim. This issue affects MLflow version through 3.10.1

Severity ?

5.1 (Medium)

CVE-2026-0545 (GCVE-0-2026-0545)

Vulnerability from cvelistv5 – Published: 2026-04-03 17:03 – Updated: 2026-04-03 17:49

Title

Missing Authentication for Critical Function in mlflow/mlflow

Summary

In mlflow/mlflow, the FastAPI job endpoints under `/ajax-api/3.0/jobs/*` are not protected by authentication or authorization when the `basic-auth` app is enabled. This vulnerability affects the latest version of the repository. If job execution is enabled (`MLFLOW_SERVER_ENABLE_JOB_EXECUTION=true`) and any job function is allowlisted, any network client can submit, read, search, and cancel jobs without credentials, bypassing basic-auth entirely. This can lead to unauthenticated remote code execution if allowed jobs perform privileged actions such as shell execution or filesystem changes. Even if jobs are deemed safe, this still constitutes an authentication bypass, potentially resulting in job spam, denial of service (DoS), or data exposure in job results.

Severity ?

CVE-2026-0596 (GCVE-0-2026-0596)

Vulnerability from cvelistv5 – Published: 2026-03-31 14:25 – Updated: 2026-04-01 03:55

Title

Command Injection in mlflow/mlflow

Summary

A command injection vulnerability exists in mlflow/mlflow when serving a model with `enable_mlserver=True`. The `model_uri` is embedded directly into a shell command executed via `bash -c` without proper sanitization. If the `model_uri` contains shell metacharacters, such as `$()` or backticks, it allows for command substitution and execution of attacker-controlled commands. This vulnerability affects the latest version of mlflow/mlflow and can lead to privilege escalation if a higher-privileged service serves models from a directory writable by lower-privileged users.

Severity ?

9.6 (Critical)

CVE-2025-15031 (GCVE-0-2025-15031)

Vulnerability from cvelistv5 – Published: 2026-03-18 22:06 – Updated: 2026-03-19 13:52

Title

Path Traversal Vulnerability in mlflow/mlflow

Summary

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 extraction directory. This issue affects the latest version of MLflow and poses a high/critical risk in scenarios involving multi-tenant environments or ingestion of untrusted artifacts, as it can lead to arbitrary file overwrites and potential remote code execution.

Severity ?

8.1 (High)

CVE-2025-14287 (GCVE-0-2025-14287)

Vulnerability from cvelistv5 – Published: 2026-03-15 09:27 – Updated: 2026-03-17 12:44

Title

Command Injection in mlflow/mlflow

Summary

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, which are then executed using `os.system()`. This allows attackers to execute arbitrary commands by supplying malicious input through the `--container` parameter of the CLI. The issue affects environments where MLflow is used, including development setups, CI/CD pipelines, and cloud deployments.

Severity ?

7.5 (High)

CVE-2025-10279 (GCVE-0-2025-10279)

Vulnerability from cvelistv5 – Published: 2026-02-02 10:36 – Updated: 2026-02-02 17:48

Title

Privilege Escalation in mlflow/mlflow

Summary

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 environment, leading to arbitrary code execution. The issue is resolved in version 3.4.0.

Severity ?

DNS Rebinding Vulnerability in mlflow/mlflow

Summary

MLFlow versions up to and including 3.4.0 are vulnerable to DNS rebinding attacks due to a lack of Origin header validation in the MLFlow REST server. This vulnerability allows malicious websites to bypass Same-Origin Policy protections and execute unauthorized calls against REST endpoints. An attacker can query, update, and delete experiments via the affected endpoints, leading to potential data exfiltration, destruction, or manipulation. The issue is resolved in version 3.5.0.

Severity ?

8.1 (High)

CVE-2025-0453 (GCVE-0-2025-0453)

Vulnerability from cvelistv5 – Published: 2025-03-20 10:11 – Updated: 2025-10-15 12:50

Title

Denial of Service through Batched Queries in GraphQL in mlflow/mlflow

Summary

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 respond to other requests. This vulnerability is due to uncontrolled resource consumption.

Severity ?
