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.
  • EPSS is 0.20% 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.

Summary
A flaw was found in Grafana. The application fails to verify creation permissions on destination folders during panel update operations. An authenticated user with edit permissions in one folder can exploit this vulnerability through the library elements API to move a library panel into a folder where they only possess view permissions. This allows an unauthorized user to bypass access controls and place content into restricted folders.

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

  • 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
An authenticated user with edit permission on one folder can move a library panel into another folder where they only have view permission, through the library elements API or the equivalent App Platform resource. The update path did not check library panel create permission on the destination folder (incorrect authorization). No data from the destination folder is disclosed, and existing content there cannot be changed.

01

What, why and how

An authenticated user with edit permission on one folder can move a library panel into another folder where they only have view permission, through the library elements API or the equivalent App Platform resource. The update path did not check library panel create permission on the destination folder (incorrect authorization). No data from the destination folder is disclosed, and existing content there cannot be changed.

What

An authenticated user with edit permission on one folder can move a library panel into another folder where they only have view permission, through the library elements API or the equivalent App Platform resource. The update path did not check library panel create permission on the destination folder (incorrect authorization). No data from the destination folder is disclosed, and existing content there cannot be changed.

Why

The application performs an authorisation check, but it does not correctly enforce the required permission boundary.

How

An attacker operating through a network path may attempt exploitation with low privileges. 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.

Likely attack path

CWE-863 ↗

CWE-863: Incorrect Authorization. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.

?CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity.

Common Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.

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
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.
