Understanding the Grafana SCIM Vulnerability

On November 21, 2025, Grafana Labs released security updates to address a critical security flaw, CVE-2025-41115 (CVSS 10.0), that could lead to privilege escalation or user impersonation in specific configurations. This vulnerability resides within the System for Cross-domain Identity Management (SCIM) component, a feature designed for automated user provisioning and management, currently in public preview.

The vulnerability, tracked as CVE-2025-41115, impacts Grafana Enterprise versions 12.0.0 to 12.2.1. According to Grafana’s advisory, the flaw lies in how user identities are handled when SCIM provisioning is enabled and configured. A malicious or compromised SCIM client can exploit this by provisioning a user with a numeric `externalId`. This can override internal user IDs, potentially leading to impersonation or privilege escalation.

The key condition for successful exploitation is having both the `enableSCIM` feature flag and the `user_sync_enabled` configuration option (within the `[auth.scim]` block) set to `true`. If these conditions are met, Grafana maps the SCIM `externalId` directly to the internal `user.uid`. Numeric values assigned as `externalId` (e.g., ‘1’) may be misinterpreted as existing internal numeric user IDs. This misinterpretation could allow a newly provisioned user to be treated as an existing internal account, such as the Admin, enabling potential impersonation or privilege escalation.

This type of vulnerability highlights the importance of secure identity management practices and the potential risks associated with misconfigured or vulnerable identity provisioning systems. Organizations using Grafana Enterprise should verify their SCIM configurations and apply the necessary patches to mitigate this risk.

Remediation Measures

Grafana has addressed this vulnerability in the following versions:

  • Grafana Enterprise 12.0.6+security-01
  • Grafana Enterprise 12.1.3+security-01
  • Grafana Enterprise 12.2.1+security-01
  • Grafana Enterprise 12.3.0

Users of affected Grafana Enterprise versions are strongly advised to upgrade to one of these patched versions as soon as possible. The analytics and observability platform discovered the vulnerability internally on November 4, 2025, during an audit and testing. Given the severity of the issue, users are advised to apply the patches as soon as possible to mitigate potential risks.

Practical Takeaways and Actionable Advice

For Technical Readers:

  1. Immediate Patching: Prioritize upgrading to a patched version of Grafana Enterprise. Verify that the upgrade is successful and that the patched version is running.
  2. Configuration Review: If immediate patching isn’t possible, review your Grafana configuration to ensure that both the `enableSCIM` feature flag and the `user_sync_enabled` option are not simultaneously enabled. Disabling either one of these can prevent exploitation.
  3. SCIM Client Security: Audit and secure your SCIM client. Ensure it’s not compromised and follows the principle of least privilege.
  4. Monitoring: Implement monitoring and alerting for any unusual user provisioning activities, especially those involving numeric `externalId` values.
  5. Regular Audits: Conduct regular security audits of your Grafana deployment, including SCIM configuration, to identify and address potential vulnerabilities.

For Non-Technical Readers (Business Leaders):

  1. Risk Assessment: Understand the potential impact of this vulnerability on your organization. Privilege escalation or user impersonation can lead to data breaches, unauthorized access to sensitive information, and disruption of services.
  2. Prioritize Patching: Work with your technical teams to prioritize the patching of Grafana Enterprise instances. Ensure that patching efforts are properly resourced and tracked.
  3. Communication: Establish clear communication channels between security, IT, and business teams to ensure timely dissemination of security information and coordinated response to vulnerabilities.
  4. SCIM Review: Ensure your IT team reviews the SCIM configuration within Grafana. Confirm that only authorized personnel and systems can provision users and that these processes adhere to security best practices.
  5. Security Awareness: Promote security awareness among employees to recognize and report any suspicious activities related to user accounts or access privileges.
