# CVE-2025-15036: MLFlow path traversal vulnerability

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.6% , percentile 47: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 47% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes mlflow (PyPI) < 3.9.0rc0, fixed in 3.9.0rc0 . Check your lockfile, including transitive dependencies.

## What it is

A path traversal vulnerability exists in the extractarchivetodir function within the mlflow/pyfunc/dbconnectartifactcache.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.

## Affected packages

- PyPI `mlflow` < 3.9.0rc0 → fixed: 3.9.0rc0

## Affected products (CVE record)

- mlflow mlflow/mlflow: unspecified < 3.9.0

## Severity

- @huntr_ai CVSS 3.0: 9.6 `CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`
- redhat-SADP CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.6 `CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.58% probability of exploitation activity in the next 30 days; percentile 47.
