# Metabase Zero-Day Gives Attackers Admin Access Without a Password — and It's Already Being Exploited

## The Threat

A zero-day vulnerability in Metabase — the open-source business intelligence platform used by tens of thousands of organizations — is being actively exploited in the wild, and the attack requires no credentials, no social engineering, and no prior foothold. An unauthenticated remote attacker can inject arbitrary SQL directly into the Metabase application database, ultimately achieving administrative access to the platform and everything it connects to.

That last part deserves emphasis: Metabase is not a peripheral tool. Organizations deploy it precisely because it has privileged read access to their most sensitive data stores — production databases, data warehouses, financial records, customer PII. When an attacker gains admin control over Metabase, they inherit its database connections. This isn't just a compromised dashboard; it's a direct path into the underlying data infrastructure.

The flaw carries a maximum CVSS score of 10.0, placing it in rare company. No CVE identifier has been assigned yet, which means automated vulnerability scanners won't flag it. Organizations relying solely on CVE feeds for patching prioritization have a blind spot here, right now, on a vulnerability being actively weaponized.

## Severity and Impact

| Field | Detail |
|---|---|
| CVE | Not yet assigned |
| CVSS Score | 10.0 (Critical) |
| CVSS Vector | AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H |
| CWE | CWE-89 (SQL Injection) |
| Attack Complexity | Low |
| Authentication Required | None |
| User Interaction Required | None |
| Exploitation Status | Actively exploited in the wild (zero-day) |
| Remote Exploitable | Yes |

## Affected Products

- **Metabase Open Source** — specific versions pending full disclosure; all installations should be treated as affected until patched
- **Metabase Enterprise** — same underlying codebase; enterprise deployments are not exempt
- **Self-hosted instances** — any Metabase deployment exposed to the internet or untrusted networks is at risk
- **Cloud-hosted via Metabase Cloud** — Metabase has indicated they are patching managed instances; verify status directly with the vendor

*Note: Because a CVE has not yet been issued, version-range specifics from the vendor advisory should be consulted directly and treated as authoritative over any third-party source.*

## Mitigations

**Immediate actions — apply before end of business:**

- **Patch now.** Metabase has released a security fix; pull the updated version immediately. Do not wait for your normal patch cycle.
- **Verify your exposure.** Check whether your Metabase instance is reachable from the public internet or from untrusted internal segments. If it is, assume it may already be compromised.
- **Audit admin accounts.** Look for newly created admin users, unexpected API keys, or changes to database connection credentials within Metabase's admin panel.
- **Review database connection logs.** Metabase's connected data sources may have received anomalous queries. Pull logs from those databases and look for unusual SQL activity originating from the Metabase service account.
- **Network segmentation.** Metabase should never be directly internet-facing without authentication at the network layer. Place it behind a VPN or zero-trust access gateway. Restrict egress from the Metabase host to only the databases it legitimately needs.
- **Rotate credentials.** Any database credentials stored in Metabase should be treated as potentially compromised. Rotate service account passwords for all connected data sources.
- **Enable alerting on admin privilege changes.** If you're not already monitoring for new admin user creation or permission escalation within Metabase, configure that now.

For organizations that cannot patch immediately: taking Metabase offline entirely is preferable to leaving an actively exploited maximum-severity vulnerability exposed.

## HackWire Analysis

This is not Metabase's first rodeo with critical unauthenticated vulnerabilities. In 2023, CVE-2023-38646 exposed Metabase installations to unauthenticated remote code execution through a flaw in the database connection setup endpoint — a vulnerability that was also rapidly weaponized after public disclosure. The pattern here is consistent: Metabase's architecture, which necessarily bridges a user-facing application layer to sensitive backend databases, creates a high-value attack surface. When that bridge breaks, the consequences are severe.

What makes the current situation more dangerous than a typical critical CVE is the timing gap created by the missing identifier. Security teams triaging vulnerability queues work from CVE lists. Threat intelligence feeds key on CVE numbers. Patch management platforms track CVEs. An actively exploited vulnerability without one slips through every automated filter — exactly the kind of gap that attackers exploit between disclosure and remediation.

There is also a sector-specific risk worth flagging: Metabase is disproportionately popular with startups, scale-ups, and data-forward SMBs that often run lean security teams and aggressive deployment practices. These organizations frequently expose Metabase directly to the internet for remote analyst access, without VPN requirements. That convenience calculus just became catastrophic.

For defenders: the absence of a CVE is not a reason to deprioritize this. If anything, treat it as a signal to move faster — the attackers already know about it, and your scanner doesn't. For larger enterprises running Metabase internally: check your network segmentation now, because a compromised Metabase instance on your internal network is a stepping stone to your data warehouse, your analytics databases, and anywhere else you've pointed it.
