Description
Grafana is an open-source platform for monitoring and observability. In affected versions when a data source has the Forward OAuth Identity feature enabled, sending a query to that datasource with an API token (and no other user credentials) will forward the OAuth Identity of the most recently logged-in user. This can allow API token holders to retrieve data for which they may not have intended access. This attack relies on the Grafana instance having data sources that support the Forward OAuth Identity feature, the Grafana instance having a data source with the Forward OAuth Identity feature toggled on, the Grafana instance having OAuth enabled, and the Grafana instance having usable API keys. This issue has been patched in versions 7.5.13 and 8.3.4.
Understanding This Vulnerability
This Common Vulnerabilities and Exposures (CVE) entry provides detailed information about a security vulnerability that has been publicly disclosed. CVEs are standardized identifiers assigned by MITRE Corporation to track and catalog security vulnerabilities across software and hardware products.
The severity rating (MEDIUM) indicates the potential impact of this vulnerability based on the CVSS (Common Vulnerability Scoring System) framework. Higher severity ratings typically indicate vulnerabilities that could lead to more significant security breaches if exploited. Security teams should prioritize remediation efforts based on severity, exploit availability, and the EPSS (Exploit Prediction Scoring System) score, which predicts the likelihood of exploitation in the wild.
If this vulnerability affects products or systems in your infrastructure, we recommend reviewing the affected products section, checking for available patches or updates from vendors, and implementing recommended workarounds or solutions until a permanent fix is available. Organizations should also monitor security advisories and threat intelligence feeds for updates about active exploitation of this vulnerability.
