What is the EPSS score for GHSA-q53q-gxq9-mgrj?

GHSA-q53q-gxq9-mgrj has an EPSS (Exploit Prediction Scoring System) score of 95.1%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

What type of vulnerability is GHSA-q53q-gxq9-mgrj?

GHSA-q53q-gxq9-mgrj is classified as Cross-site Scripting (XSS) (CWE-79), Open Redirect (CWE-601). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Is there exploit tooling available for GHSA-q53q-gxq9-mgrj?

A Nuclei detection template exists for GHSA-q53q-gxq9-mgrj, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was GHSA-q53q-gxq9-mgrj published, and has it been updated?

GHSA-q53q-gxq9-mgrj was published on May 22, 2025 and was last updated on May 6, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

A cross-site scripting (XSS) vulnerability exists in Grafana caused by combining a client path traversal and open redirect. This allows attackers to redirect users to a website that hosts a frontend plugin that will execute arbitrary JavaScript. This vulnerability does not require editor permissions and if anonymous access is enabled, the XSS will work. If the Grafana Image Renderer plugin is installed, it is possible to exploit the open redirect to achieve a full read SSRF.

The default Content-Security-Policy (CSP) in Grafana will block the XSS though the connect-src directive.
