Cross-Site Scripting in Grafana Explore Traces via Jaeger HTTP

Publication date: 2026-02-12

Last updated on: 2026-02-26

Assigner: Grafana Labs

Description
Stack traces in Grafana's Explore Traces view can be rendered as raw HTML, and thus inject malicious JavaScript in the browser. This would require malicious JavaScript to be entered into the stack trace field. Only datasources with the Jaeger HTTP API appear to be affected; Jaeger gRPC and Tempo do not appear affected whatsoever.

Executive Summary

This vulnerability involves Grafana's Explore Traces view rendering stack traces as raw HTML. Because of this, if malicious JavaScript code is entered into the stack trace field, it can be injected and executed in the user's browser.

Only datasources using the Jaeger HTTP API are affected by this issue; other datasources like Jaeger gRPC and Tempo are not impacted.

Impact Analysis

The vulnerability can lead to the execution of malicious JavaScript in the browser of anyone viewing the affected stack traces. This can result in potential compromise of user data confidentiality and integrity.

Since the CVSS score indicates high impact on confidentiality and integrity, an attacker could use this to steal sensitive information or manipulate data displayed in the Grafana interface.
