Who should care

Defenders responsible for Grafana instance configurations, user permissions, and monitoring should assess exposure and prioritize verification. This includes reviewing the current configurations, user permissions, and monitoring for suspicious activity. Additionally, defenders should verify the vulnerability's impact on their specific Grafana instance configurations and take necessary actions to prevent potential unauthorized access and compromise of third

Why it matters

CVE-2025-12141 is a low-severity vulnerability in Grafana's alerting system that could lead to unauthorized access and potential compromise of external integrations. Defenders should prioritize verifying Grafana instance configurations, reviewing user permissions, and monitoring for suspicious activity.

• Potential unauthorized access to external integrations
• Possible compromise of third-party service credentials
• Need for verification of Grafana instance configurations
• Requirement for monitoring suspicious activity

Technical summary

The vulnerability exists in Grafana's alerting system, where users with edit permissions for a contact point can modify the endpoint URL to a controlled server. By invoking the test functionality, attackers can capture and extract redacted secure settings, such as authentication credentials for third-party services. This could lead to unauthorized access and potential compromise of external integrations. The vulnerability has a CVSS score of 1.3 and is considered low-severity. However, defenders should still prioritize verifying Grafana instance configurations, reviewing user permissions, and monitoring for suspicious activity.

Defensive priority

Defenders should prioritize verifying Grafana instance configurations, reviewing user permissions, and monitoring for suspicious activity.

Recommended defensive actions

• Verify Grafana instance configurations and user permissions
• Monitor for suspicious activity
• Review and update secure settings for third-party services
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
• Check relevant monitoring, detection, and logs for exposed assets that need extra review

Evidence notes

The CVE record and NVD entry provide details on the vulnerability, including its description, CVSS score, and affected versions. However, the information available is limited, and defenders should verify the vulnerability's impact on their specific Grafana instance configurations. The CVE Program and NVD entries provide source-provided CVE metadata and official vulnerability assessments, respectively. However, additional verification is necessary to confirm the vulnerability's existence and potential impact.
