# CVE-2023-6018: Remote Code Execution due to Full Controled File Write in mlflow

**Signal:** High exploit likelihood. EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- No confirmed exploitation. It is not in CISA’s KEV catalog. That can change quickly after a public write-up; re-check if you are affected.
- EPSS 47.9% , percentile 99: FIRST’s model estimates a 47.9% chance of exploitation activity in the next 30 days, higher than 99% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- Only applies if your dependency tree includes mlflow (PyPI) <= 2.8.1, fixed in 2.9.2 . Check your lockfile, including transitive dependencies.

## What it is

An attacker can overwrite any file on the server hosting MLflow without any authentication.

## Affected packages

- PyPI `mlflow` <= 2.8.1 → fixed: 2.9.2

## Affected products (CVE record)

- mlflow mlflow/mlflow: unspecified <= latest

## Severity

- @huntr_ai CVSS 3.0: 10 `CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 10.0 `CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- FIRST EPSS (model of 2026-10-21): 47.87% probability of exploitation activity in the next 30 days; percentile 99.
