CVE-2025-41117Network attack vectorHinoki check available

Stored XSS via unsanitized trace HTML rendering

Published Feb 12, 2026 · Updated Feb 12, 2026

Stored XSS in Grafana and Grafana Enterprise allows remote attackers to run JavaScript in a trace viewer's browser via malicious trace data. The TraceView KeyValuesTable sends unsanitized stack-trace values to React's dangerouslySetInnerHTML, which treats them as executable markup. Exploitation requires attacker-controlled JavaScript in a Jaeger HTTP stack-trace field and a user who opens the trace, exposing that user's Grafana-origin data and actions; Jaeger gRPC and Tempo are unaffected.
