CVE-2026-111024: 
Grafana Analyse et atténuation de la vulnérabilité

CVE-2026-111024 is an incorrect authorization vulnerability in Grafana's repository files API that allows authenticated users with Viewer or Editor roles to bypass folder permissions on Git Sync managed resources. Viewers can read files in restricted folders, while Editors can create, modify, move, or delete provisioned dashboards and folders beyond their permitted scope. The vulnerability affects Grafana OSS and Grafana Enterprise versions 13.0.2–13.0.12, 13.1.0–13.1.9, 13.2.0–13.2.5, and 13.3.0. It was published on November 11, 2026, with a CVSS v3.1 base score of 7.1 (High) (GitHub Advisory, Grafana Advisory).

The root cause is an incorrect authorization check (CWE-863) in Grafana's repository files API, which fails to enforce folder-level permissions for Git Sync managed resources — a "failing open" behavior (CWE-636). When authenticated users interact with the repository files API endpoint, the API does not properly validate whether the requesting user's role grants access to the target folder, allowing permission boundaries to be bypassed. The attack requires only low privileges (a valid Viewer or Editor account), no user interaction, and is exploitable over the network with low complexity. No public proof-of-concept code has been identified at this time (GitHub Advisory, Grafana Advisory).

Exploitation allows any authenticated Viewer to read sensitive dashboard configurations or data source files stored in restricted Git Sync folders, resulting in a low confidentiality impact. More critically, authenticated Editors can create, modify, move, or delete provisioned dashboards and folders they should not have access to, representing a high integrity impact. Availability is not directly affected, but unauthorized deletion or modification of dashboards could disrupt monitoring operations. The scope is limited to the Grafana instance itself, but exposure of dashboard configurations could facilitate further reconnaissance or privilege escalation within the monitored environment (GitHub Advisory, Grafana Advisory).

There is no evidence of active in-the-wild exploitation or publicly available proof-of-concept code as of the disclosure date (GitHub Advisory). The EPSS score is 0.0, indicating a currently low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been reported. However, the low attack complexity and minimal privilege requirement (any authenticated user) make it a relatively accessible target if exploited.

1. Reconnaissance: Identify a Grafana instance running a vulnerable version (13.0.2–13.0.12, 13.1.0–13.1.9, 13.2.0–13.2.5, or 13.3.0) with Git Sync enabled, using version disclosure from the Grafana UI or API endpoints.
2. Authenticate: Log in with any valid Grafana account holding a Viewer or Editor role — no elevated privileges are required.
3. Enumerate repository files API: Send authenticated HTTP requests to the Grafana repository files API endpoint (e.g., /api/v1/provisioning/folders or the Git Sync repository files path) to list available folders and files, including those in restricted directories.
4. Viewer exploitation — read restricted files: As a Viewer, craft API requests targeting folder paths that the account should not have read access to, leveraging the missing authorization check to retrieve dashboard JSON or configuration files.
5. Editor exploitation — modify or delete resources: As an Editor, send API requests to create, update, move, or delete provisioned dashboards and folders in restricted paths, bypassing the intended folder permission boundaries.
6. Exfiltrate or tamper: Extract sensitive dashboard configurations for reconnaissance, or alter/delete critical dashboards to disrupt monitoring visibility (GitHub Advisory, Grafana Advisory).

• Network: Unusual authenticated API requests to Grafana's repository files API endpoints from Viewer or Editor accounts, particularly targeting folder paths outside their normal access scope; repeated enumeration of folder/file paths via the API.
• Logs: Grafana audit logs showing Viewer-role accounts performing file read operations on restricted folders; Editor-role accounts performing create, update, move, or delete operations on provisioned dashboards or folders they do not own; unexpected access patterns in Grafana's HTTP access logs for /api/v1/provisioning/ or Git Sync-related API paths.
• File System: Unexpected modifications, deletions, or additions to provisioned dashboard JSON files managed by Git Sync; changes to folder structures in the Grafana provisioning directory not initiated by authorized administrators.

Grafana has released patched versions addressing this vulnerability: upgrade Grafana OSS or Grafana Enterprise to versions 13.0.13, 13.1.10, 13.2.6, or 13.3.1 (or later) (GitHub Advisory, Grafana Advisory). As interim mitigations, restrict API access to trusted users only, audit and tighten folder permission configurations in Git Sync, and review audit logs for unauthorized file operations via the repository files API. Organizations should prioritize upgrading instances where Git Sync is actively used and where Viewer or Editor roles are granted to untrusted users.
