CVE-2026-27464 in Metabase
Summary
by MITRE • 02/21/2026
Metabase is an open-source data analytics platform. In versions prior to 0.57.13 and versions 0.58.x through 0.58.6, authenticated users are able to retrieve sensitive information from a Metabase instance, including database access credentials. During testing, it was confirmed that a low-privileged user can extract sensitive information including database credentials, into the email body via template evaluation. This issue has been fixed in versions 0.57.13 and 0.58.7. To workaround this issue, users can disable notifications in their Metabase instance to disallow access to the vulnerable endpoints.

CVE-2026-27464 represents a critical information disclosure vulnerability within the Metabase data analytics platform that affects multiple version ranges including pre-0.57.13 and 0.58.x through 0.58.6 releases. This vulnerability stems from insufficient access controls and improper input validation within the template evaluation system that allows authenticated users to exploit a path traversal or information leakage mechanism. The flaw specifically manifests when low-privileged users can manipulate template parameters to extract sensitive database credentials and other confidential information that should remain protected within the system. The vulnerability operates through the notification system where template evaluation processes are improperly sanitized, allowing malicious users to inject payloads that can retrieve and expose stored credentials.
The technical implementation of this vulnerability aligns with CWE-200, which describes improper exposure of sensitive information, and CWE-79, which covers cross-site scripting vulnerabilities that can be leveraged for information disclosure. Attackers can exploit this weakness by crafting specific template parameters that bypass normal access controls, enabling them to retrieve database connection strings, user credentials, and potentially other sensitive configuration data. The impact extends beyond simple credential theft as this information can be used for lateral movement within the network, database access, and further exploitation of connected systems. The vulnerability demonstrates a classic case of insufficient privilege enforcement where the system fails to properly validate user permissions before allowing access to sensitive data retrieval functions.
The operational implications of this vulnerability are severe for organizations relying on Metabase for data analytics and business intelligence operations. A compromised low-privileged user account can escalate their access to obtain database credentials that may provide access to production databases containing sensitive organizational data. This creates a significant risk for data breaches, unauthorized data access, and potential compliance violations under regulations such as gdpr, hipaa, and pci dss. The vulnerability affects not only the immediate data exposure but also creates opportunities for attackers to establish persistent access through stolen credentials, potentially leading to extended compromise of the entire data infrastructure.
Organizations should immediately upgrade to Metabase versions 0.57.13 or 0.58.7 to remediate this vulnerability, as these releases contain the necessary patches to address the template evaluation flaws and access control issues. The recommended mitigation strategy includes implementing the workaround of disabling notifications within the Metabase instance to prevent access to the vulnerable endpoints, though this approach may limit legitimate notification functionality. Security teams should also conduct comprehensive audits of their Metabase deployments to identify any unauthorized access or credential exposure that may have occurred during the vulnerability window. Additionally, organizations should implement network monitoring to detect unusual template evaluation patterns or credential retrieval attempts that could indicate exploitation of this vulnerability. The ATT&CK framework categorizes this vulnerability under T1566 for credential access and T1071 for application layer protocol usage, making it a critical target for both defensive and offensive security operations.
