Summary
CVE-2025-6023 is a high-severity Cross-site Scripting (CWE-79) vulnerability in Grafana OSS (inferred from references). Its CVSS base score is 7.6 (High).
Operationally, ranked in the top 8.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
An open redirect vulnerability has been identified in Grafana OSS that can be exploited to achieve XSS attacks. The vulnerability was introduced in Grafana v11.5.0 and can be chained with path traversal vulnerabilities to achieve XSS. It is tracked under CWE-79 and CWE-601 with a CVSS 3.1 score of 7.6.
Unauthenticated remote attackers can supply crafted URLs that trigger the open redirect, leading victims to attacker-controlled destinations where malicious scripts execute in the context of the Grafana instance. Successful exploitation can result in theft of sensitive data, session hijacking, or limited modification of application state.
Grafana has published fixes in versions 12.0.2+security-01, 11.6.3+security-01, 11.5.6+security-01, 11.4.6+security-01, and 11.3.8+security-01. The vendor advisory and accompanying blog post recommend immediate upgrade to one of the patched releases and note that the issue affects all prior 11.5.x and later builds prior to these updates. The associated EPSS score has remained low and essentially flat since disclosure.
