CVE-2021-41277

CVE-2021-41277 is a critical-severity (CVSS 10.0) vulnerability in Metabase Metabase. CISA added it to the Known Exploited Vulnerabilities catalog on November 12, 2024, which means exploitation in the wild has been confirmed; US federal agencies had to remediate it by December 3, 2024. CISA does not currently list it as used in ransomware campaigns. Metabase has 2 vulnerabilities in the KEV catalog, 0 of them linked to ransomware.

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.
