CVE-2026-9029: Stored XSS in the Geomap panel tile-layer attribution
A user with Editor permissions can place a malicious script in the attribution field of a Geomap panel's XYZ tile layer via a template variable. The script then executes in the browser of any user who views the affected dashboard (stored cross-site scripting).
Security readout for executives and security teams
Plain-English summary
CVE-2026-9029 is a stored cross-site scripting issue in Grafana OSS Geomap panels. An Editor can save script content through a template-variable-backed XYZ tile-layer attribution field, causing it to run when another user views the dashboard.
Executive priority
Treat as high priority for Grafana environments where Editors are not fully trusted or dashboards are viewed by privileged users. The main concern is browser-side execution affecting confidentiality and integrity.
Technical view
The issue is CWE-79 stored XSS affecting Grafana OSS 12.4.0 and 13.0.0. The CVSS 3.1 score is 7.3, with network access, low attack complexity, low privileges, and required user interaction. Reported impact is high confidentiality and integrity loss, no availability impact.
Likely exposure
Exposure is limited to Grafana OSS deployments running listed versions 12.4.0 or 13.0.0 with users who have Editor permissions and Geomap dashboards using XYZ tile-layer attribution via template variables.
Exploitation context
The bundle does not show KEV listing or active exploitation evidence. Exploitation requires an authenticated Editor to store malicious content and another user to view the affected dashboard, so risk depends heavily on editor trust boundaries.
Researcher notes
Evidence supports stored XSS through the Geomap panel XYZ tile-layer attribution field using a template variable. Do not assume impact beyond Grafana OSS 12.4.0 and 13.0.0 unless vendor sources add more affected versions.
Mitigation direction
Check Grafana's advisory for fixed versions or vendor-recommended actions.
Upgrade affected Grafana OSS instances according to vendor guidance.
Restrict Editor permissions to trusted users until remediation is complete.
Review dashboard change history for suspicious Geomap tile-layer attribution changes.
Validation and detection
Inventory Grafana OSS versions and flag 12.4.0 and 13.0.0.
Identify dashboards using Geomap panels with XYZ tile layers.
Review template variables used in tile-layer attribution fields.
Confirm Editor role assignments are appropriate for each Grafana organization.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
