Recommended action
Patch only the product branches with a verified fix

Medium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority. Verified remediation exists for at least one product or source, but 2 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Evidence used

  • No CISA KEV confirmation is currently recorded.
  • The selected CVSS metric records a network-reachable, unauthenticated path with no user interaction.
  • EPSS is 0.37% for the current model date.

Compensating controls

  • Validate the affected product branch and deploy the verified fixed release.
  • Restrict the affected network interface to trusted sources where business-safe.
  • Monitor vendor guidance and exploitation sources for a material change.

Verification

  1. Confirm that the asset runs Grafana Grafana Enterprise and falls inside the recorded affected range.
  2. Verify the installed build against the product-specific fixed version after deployment.
  3. Validate exposure, authentication requirements and compensating controls in the actual environment.
  4. Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Mitigation target: As exposure requiresRemediation target: Within 365 days

This automated reassessment organises public evidence. It does not know asset exposure, business impact or control effectiveness and does not replace CVSS or a human risk decision.

Cross-source reconciliation

Remediation availability differs by product scope

Verified remediation exists for at least one product or source, but 2 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

  • grafana as component of SUSE Linux Enterprise Module for Package Hub 15 SP7
  • grafana as component of SUSE Multi-Linux Manager Client Tools for SLE 15
Summary
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.

CVE-2026-81841 · CSAF 2.0 · revision 3 · finalRed Hat Product Securitygrafana: grafana: Information disclosure via unrevoked access tokens in paused shared dashboards
5 known affected

The vendor explicitly identifies these products as affected by this CVE.

  • multicluster-globalhub/multicluster-globalhub-grafana-rhel9 as a component of Multicluster Global Hub
  • rhacm2/acm-grafana-rhel9 as a component of Red Hat Advanced Cluster Management for Kubernetes 2
  • grafana as a component of Red Hat Enterprise Linux 10
  • grafana-selinux as a component of Red Hat Enterprise Linux 10
  • grafana.src as a component of Red Hat Enterprise Linux 10
Summary
A flaw was found in Grafana. This vulnerability allows information disclosure because pausing a shared dashboard fails to revoke access tokens for endpoints serving initialization data. An unauthenticated remote attacker possessing the link to a paused dashboard can exploit this flaw to retrieve sensitive data source configurations, potentially exposing stored credentials.

01

What, why and how

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.

What

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.

Why

The application reaches a protected operation without first confirming that the requester is authorised.

How

An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

Exploit reality and attack path

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.

Observed exploitation
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
No confirmed evidence

No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.

Public PoC / exploit material
?Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.
None recorded

No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

Patch and workaround

Operational remediation based on structured source evidence.

Status
?Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change.
Fix availability varies by product
Affected
Fixed
For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/
Action
Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
Workaround
No verified workaround is recorded. If business-safe, reduce exposure to the affected interface and allow only trusted sources until authoritative guidance is available.
