CVE-2026-8595· NVD / CVE Program· CNA GRAFANA

Stored XSS in the table panel (TableNG)

Noroxi assessment

Priority: Monitor (action score 21/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.30% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: grafana (openSUSE:Leap 16.0) 12.4.5-bp160.2.1; grafana (openSUSE:Tumbleweed) 12.4.5-3.1; grafana12.4 (Red Hat:hummingbird:1) 0:12.4.10-0.1.hum1.

Low priority for now. Upgrade to grafana (openSUSE:Leap 16.0) 12.4.5-bp160.2.1; grafana (openSUSE:Tumbleweed) 12.4.5-3.1; grafana12.4 (Red Hat:hummingbird:1) 0:12.4.10-0.1.hum1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A user with Editor permissions can craft a dashboard whose table (TableNG) panel contains a malicious field name that executes as a script in the browser of any user who views the dashboard (stored cross-site scripting).

Limit the impact of XSS

This is a cross-site scripting (XSS) vulnerability. A well-configured Content-Security-Policy doesn't fix it, but greatly reduces its impact. Check your site's CSP and other security headers for free.

Affected versions

NVD version ranges (for catalog products). Add the product to your stack with a version and matching uses these.

  • grafana grafana12.4.0 and later · before 12.4.4
  • grafana grafana13.0.0 and later · before 13.0.2

Versions reported by the vendor

Affected version ranges reported by the assigning authority (GRAFANA). Independent of NVD's CPE analysis and usually ahead of it.
