CVE-2026-92813 metabase CVE debrief

Metabase through 0.63.18 fails to properly validate the unspecified address 0.0.0.0 in custom GeoJSON URLs, allowing unauthenticated attackers to reach loopback services. This vulnerability enables attackers to save a malicious GeoJSON entry with 0.0.0.0 and trigger requests that return loopback service responses to unauthenticated callers, potentially bypassing security controls and exposing internal services. Defenders should assess and remediate this vulnerability to prevent potential exploitation.

Who should care

Defenders responsible for Metabase instances, especially those exposed to untrusted networks, should assess and remediate this vulnerability to prevent potential exploitation of loopback services and bypass of security controls. This includes verifying Metabase instance version and exposure to untrusted networks, reviewing custom GeoJSON URLs for 0.0.0.0 address usage, and remediating vulnerable instances.

Why it matters

Defenders should prioritize verifying and remediating this vulnerability in Metabase instances, especially those exposed to untrusted networks, to prevent potential exploitation of loopback services and bypass of security controls.

  • Potential exploitation of loopback services
  • Unauthenticated access to internal services
  • Possible bypass of security controls
  • Verification of Metabase instance vulnerability

Technical summary

The vulnerability allows unauthenticated attackers to reach loopback services by saving a malicious GeoJSON entry with the address 0.0.0.0 and triggering requests that return loopback service responses. This could lead to potential exploitation of loopback services, unauthenticated access to internal services, and possible bypass of security controls. Defenders should prioritize verifying and remediating this vulnerability in Metabase instances, especially those exposed to untrusted networks, to prevent potential exploitation.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability in Metabase instances, especially those exposed to untrusted networks.

Recommended defensive actions

  • Verify Metabase instance version and exposure to untrusted networks
  • Review custom GeoJSON URLs for 0.0.0.0 address usage
  • Remediate vulnerable instances to prevent potential loopback service exploitation
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, but the scope of affected versions and potential impact require further verification. The vulnerability affects Metabase instances, especially those exposed to untrusted networks. Defenders should verify Metabase instance version and exposure to untrusted networks.
