In CISA’s Known Exploited Vulnerabilities catalog: Metabase GeoJSON API Local File Inclusion Vulnerability.

Added , federal remediation due . Known ransomware use: Unknown.

Required action: Apply mitigations per vendor instructions or discontinue use of the product if mitigations are unavailable.

Description

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.
