Executive Summary

This vulnerability is an open redirect issue in the Grafana OSS organization switching functionality. It occurs when multiple organizations exist in a Grafana instance, and a victim user is on a different organization than the one specified in a crafted URL. An attacker can exploit this to redirect the user to an untrusted external site. This can potentially be used in phishing or other social engineering attacks. The vulnerability requires user interaction and has a moderate severity score (CVSS 4.2).

Impact Analysis

The open redirect vulnerability can impact you by allowing attackers to redirect users to malicious websites, potentially leading to phishing attacks or other social engineering exploits. Although the vulnerability itself does not directly compromise confidentiality, integrity, or availability to a high degree, it can be used as a stepping stone for further attacks such as cross-site scripting (XSS) when chained with other vulnerabilities. Users might be tricked into trusting malicious sites due to the legitimate Grafana URL in the redirect.
