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.
The dashboard permissions API does not verify the target dashboard scope and only checks the dashboards.permissions:* action. As a result, a user who has permission management rights on one dashboard can read and modify permissions on other dashboards. This is an organization‑internal privilege escalation.
