# CVE-2021-41277: Metabase GeoJSON API Local File Inclusion Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Metabase Metabase. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2024-11-12, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2024-12-03 ; treat that as the outer limit, not the target.
- EPSS 97.2% , percentile 99.9: FIRST’s model estimates a 97.2% chance of exploitation activity in the next 30 days, higher than 99.9% 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.

## What it is

Metabase is an open source data analytics platform. In affected versions a security issue has been discovered with the custom GeoJSON map (admin->settings->maps->custom maps->add a map) support and potential local file inclusion (including environment variables). URLs were not validated prior to being loaded. This issue is fixed in a new maintenance release (0.40.5 and 1.40.5), and any subsequent release after that. If you’re unable to upgrade immediately, you can mitigate this by including rules in your reverse proxy or load balancer or WAF to provide a validation filter before the application.

## Affected products (CVE record)

- metabase metabase: < 0.40.5, >= 1.0.0, < 1.40.5

## Severity

- GitHub_M CVSS 3.1: 10 `CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:L`

## Exploitation

- CISA KEV: added 2024-11-12; federal due date 2024-12-03. Known ransomware use: Unknown.
- CISA required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.
- CISA SSVC assessment: exploitation active , automatable yes , technical impact total .
- FIRST EPSS (model of 2026-10-21): 97.18% probability of exploitation activity in the next 30 days; percentile 99.9.
