Grafana: Missing authorization in team preferences endpoint
Summary
Any authenticated user, including users with the Viewer role, can change the preferences of any team through an undocumented endpoint that lacks access control. These preferences include the home dashboard, theme and timezone. An attacker can therefore redirect all members of a team to a dashboard of their choice, which could support phishing or social engineering. The attacker needs a valid Grafana login, so exposure of the instance and self-registration settings determine the risk.

Fixed in
Unknown. Check the vendor advisory for the fixed versions.
Workaround
Unknown. No vendor mitigation was available at the time of writing.
- Restrict access to undocumented endpoints where possible.
- Review Viewer and shared accounts.
- Limit Grafana access to trusted networks or VPN.
Exploitation
- No public proof of concept known.
- Not known to be exploited in the wild; not listed in CISA KEV.
Our recommendation
- Check the vendor advisory for fixed builds and update to the nearest fixed release.
- Check whether Grafana is internet-facing or allows self-registration and prioritise accordingly.
- Review Viewer and shared accounts and check whether preference changes are logged.
- Monitor for unexpected team preference changes.
- Re-check exploitation status in the coming weeks.

Original description (NVD)
Any authenticated user, including a Viewer, could change the preferences of any team, such as its home dashboard, theme and timezone, through an undocumented endpoint with no access control, and so redirect every member of that team to a dashboard of their choice (missing authorization).
