CVE-2026-81841 — Paused shared dashboard access tokens still expose data source configuration
Pausing a shared (public) dashboard did not revoke its access token for the endpoints that serve frontend bootstrap data. Anyone holding the link to a paused shared dashboard could still retrieve, without authenticating, the configuration of the dashboard's data sources, including stored credentials for data sources using browser access (missing authorization). Deleting the shared dashboard does revoke the token.

Remediation
The vendor's own words where we have them.
Upgrade Grafana Enterprise to a fixed release. Apply vendor patches per advisory and restrict external exposure of the affected component until patched.
First 24 hours
Ordered from the record's own fields — exposure first, because you cannot patch what you have not found.
- Identify exposed assets running affected vendor/product/version combinations.
- Prioritize based on EPSS, PoC availability, and external exposure.
- Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class.

Answered from this record1
What should defenders know first?
CVE-2026-81841 is Paused shared dashboard access tokens still expose data source configuration, a medium vulnerability affecting Grafana Enterprise, Grafana OSS from Grafana. The current evidence does not list it in CISA KEV, and the exploit status is: Active exploitation is not confirmed from current sources for CVE-2026-81841. Public exploit evidence is: 1 public PoC repositories reported; 0 marked weaponized in current dataset. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 5.3 describes technical severity, while EPSS 0% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
