CVE-2025-8341 is a Server-Side Request Forgery (SSRF) vulnerability identified in the Grafana Infinity datasource plugin version 0.6.0. Grafana is a widely used open-source platform for monitoring and observability, and the Infinity datasource plugin enables users to visualize data from various endpoint formats including JSON, CSV, XML, GraphQL, and HTML. The vulnerability arises when the plugin is configured to restrict access to certain URLs, but an attacker can bypass these restrictions by crafting a specially designed URL. This allows the attacker to make unauthorized requests from the Grafana server to internal or external resources that would otherwise be inaccessible. The SSRF vulnerability is classified under CWE-918, indicating that the server is tricked into making unintended requests. The CVSS v3.1 base score is 5.0 (medium severity), with an attack vector of network, low attack complexity, requiring privileges (PR:L), no user interaction, and a scope change (S:C). The impact primarily affects confidentiality, as the attacker can potentially access sensitive internal resources or metadata by leveraging the SSRF, but it does not directly affect integrity or availability. The vulnerability has been fixed in version 3.4.1 of the plugin. No known exploits are currently reported in the wild.

For European organizations, this SSRF vulnerability in the Grafana Infinity datasource plugin poses a moderate risk. Many enterprises and public sector organizations in Europe rely on Grafana for monitoring critical infrastructure, applications, and services. An attacker exploiting this vulnerability could access internal network resources, potentially exposing sensitive information such as internal APIs, metadata services, or other protected endpoints. This could lead to reconnaissance for further attacks or data leakage. Since the vulnerability requires some level of privileges on the Grafana instance, the risk is higher in environments where Grafana is accessible to multiple users or integrated with other systems. The confidentiality breach could be significant in sectors like finance, healthcare, energy, and government, where internal data exposure can have regulatory and operational consequences. However, the lack of impact on integrity and availability limits the potential for direct disruption or data manipulation.

To mitigate this vulnerability, European organizations should promptly upgrade the Grafana Infinity datasource plugin to version 3.4.1 or later, where the SSRF issue is fixed. Additionally, organizations should review and tighten access controls on Grafana instances, ensuring that only trusted users have privileges to configure or use the Infinity datasource plugin. Network segmentation should be enforced to limit the Grafana server's ability to reach sensitive internal endpoints. Implementing strict egress filtering and firewall rules can prevent unauthorized outbound requests initiated by the plugin. Monitoring and logging of Grafana datasource requests should be enhanced to detect unusual or suspicious activity indicative of SSRF exploitation attempts. Finally, organizations should conduct security assessments and penetration tests focusing on SSRF vectors within their monitoring infrastructure to identify and remediate any residual risks.
