Critical Metabase SQL Injection Zero-Day Vulnerability Discovered
Executive Summary
In August 2026, Metabase disclosed a critical SQL injection vulnerability affecting versions 1.58 and above of its Cloud platform. This flaw allowed remote attackers to inject SQL statements into the application database, granting them administrator access. Exploiting this access, attackers could alter configurations, steal stored credentials, and access connected databases. Metabase promptly blocked the exploited endpoints and released patches to address the vulnerability. Self-hosted instances with exposed /api/session/reset_password endpoints remained at risk until updated. This incident underscores the persistent threat posed by SQL injection vulnerabilities, which continue to be prevalent despite longstanding awareness. Organizations are reminded of the importance of implementing prepared statements and other secure coding practices to mitigate such risks.
Why This Matters Now
The Metabase SQL injection zero-day highlights the ongoing challenges in securing web applications against injection attacks. With attackers actively exploiting such vulnerabilities, organizations must prioritize timely patching and robust security measures to protect sensitive data and maintain trust.
Attack Path Analysis
An attacker exploited a zero-day SQL injection vulnerability in Metabase Cloud to gain unauthorized administrator access. This access allowed them to manipulate application configurations and extract stored credentials, leading to unauthorized data access. The attacker then moved laterally to connected databases, exfiltrating sensitive information. Finally, the attacker potentially disrupted services by altering configurations or deleting data.
