CVE-2026-8595Network attack vector

Stored XSS via malicious TableNG field names

Published Jul 10, 2026 · Updated Jul 10, 2026

Stored XSS in Grafana OSS 12.4.0 through 12.4.3 and 13.0.0 through 13.0.1 allows remote authenticated users to execute scripts. The TableNG panel renders an attacker-controlled field name from a saved dashboard as active browser content instead of neutralizing it. Editor permission is required to store the payload, and any user who views the crafted dashboard triggers it in that user's browser.
