Internal resource disclosure via mixed DNS answers
Published Mar 28, 2025 · Updated Mar 28, 2025
SSRF in Metabase 0.52, 0.53, 1.52, and 1.53 allows remote authenticated users to read internal HTTP resources through GeoJSON URLs. The endpoint accepts a hostname whose DNS answer set mixes public and local-link addresses, then fetches an address without rejecting the full set. Exploitation requires high-privileged access, enabled GeoJSON use, repeated resolution attempts, and a self-hosted instance colocated with an unsecured resource.
