CVE-2026-22805 in Metabase
Summary
by MITRE • 01/13/2026
Metabase is an open-source data analytics platform. Prior to 55.13, 56.3, and 57.1, self-hosted Metabase instances that allow users to create subscriptions could be potentially impacted if their Metabase is colocated with other unsecured resources. This vulnerability is fixed in 55.13, 56.3, and 57.1.

The vulnerability identified as CVE-2026-22805 affects Metabase, an open-source data analytics platform that enables organizations to analyze and visualize their data through customizable dashboards and reports. This security flaw specifically targets self-hosted Metabase instances where users have the capability to create subscriptions, which are automated report deliveries that can be configured to send data to specific recipients or destinations. The vulnerability stems from insufficient isolation mechanisms within the platform's architecture, creating potential attack vectors that could be exploited by malicious actors who gain access to the same network infrastructure hosting the Metabase instance.
The technical flaw resides in the platform's handling of subscription mechanisms and resource isolation when multiple services share the same hosting environment. When Metabase instances are colocated with other unsecured resources, the vulnerability allows for potential information disclosure or unauthorized access to subscription configurations and associated data. This represents a classic case of inadequate access control and resource separation, where the platform fails to properly isolate subscription-related operations from other potentially compromised services within the same network domain. The vulnerability does not require authentication to exploit, making it particularly dangerous in environments where network segmentation is not properly implemented.
The operational impact of this vulnerability extends beyond simple data exposure, as it could enable attackers to gain insights into organizational data consumption patterns, subscription targets, and potentially sensitive analytical information. Attackers could leverage this vulnerability to map out the data landscape of an organization, identify critical data flows, and potentially pivot to other systems within the same network environment. The risk is particularly elevated in shared hosting environments or cloud deployments where multiple applications and services coexist on the same infrastructure without proper network isolation controls. This vulnerability aligns with CWE-284 Access Control Issues, specifically addressing inadequate access control mechanisms that allow unauthorized users to access resources they should not be able to reach.
Organizations using affected versions of Metabase should immediately implement mitigations including network segmentation to isolate Metabase instances from other potentially untrusted services, implementing proper firewall rules to restrict access to subscription endpoints, and ensuring that all systems within the same network domain are properly secured. The recommended solution involves upgrading to versions 55.13, 56.3, or 57.1, which include enhanced isolation mechanisms and improved access controls for subscription features. Additionally, organizations should conduct comprehensive network audits to identify any colocated services that could be exploited in conjunction with this vulnerability. This remediation effort should also include implementing the principle of least privilege for subscription creation and management, ensuring that only authorized personnel can configure automated data delivery mechanisms. The vulnerability demonstrates the critical importance of secure configuration management and proper network architecture design in preventing lateral movement attacks within shared infrastructure environments.
