CVE-2026-14242: 
Grafana Analyse et atténuation de la vulnérabilité

CVE-2026-14242 is an authorization bypass vulnerability in Grafana OSS and Grafana Enterprise that allows authenticated users with the Editor role to perform unauthorized operations on Git Sync managed resources. By crafting provisioning jobs through the jobs resource API, an Editor can delete, move, push, or pull resources in folders where they only have view-level access, bypassing folder permission checks. The vulnerability affects Grafana versions 13.0.0–13.0.12, 13.1.0–13.1.9, 13.2.0–13.2.5, and 13.3.0. It was published on November 11, 2026, and carries a CVSS v3.1 base score of 6.5 (Medium) (GitHub Advisory, Grafana Advisory).

The root cause is an incorrect authorization implementation (CWE-862: Missing Authorization) in the jobs resource API, which also reflects improper privilege management (CWE-269) and improper protection of an alternate path (CWE-424). When an Editor-role user creates a provisioning job via the jobs resource API, the code path responsible for executing Git Sync operations — such as delete, move, push, or pull — does not enforce folder-level permission checks, allowing the user to act on folders where they only hold view access. The attack requires network access and low privileges (a valid Editor account), with no user interaction needed. No public proof-of-concept or technical write-up beyond the vendor advisory is currently available (GitHub Advisory, Grafana Advisory).

Successful exploitation results in a high integrity impact: an authenticated Editor can delete, move, push, or pull Git Sync managed resources in folders they should only be able to view, potentially corrupting or destroying dashboard configurations, datasource definitions, or other provisioned resources. There is no confidentiality or availability impact identified. The scope is limited to the affected Grafana instance, but unauthorized modification or deletion of provisioned resources could disrupt monitoring infrastructure and affect downstream systems that depend on those configurations (GitHub Advisory, Grafana Advisory).

There is no evidence of active in-the-wild exploitation or a publicly available proof-of-concept at this time (Feedly). The vulnerability requires a valid Editor-role account, making it an insider threat or post-compromise escalation scenario rather than an unauthenticated attack. The EPSS score is 0.0, indicating a very low probability of exploitation in the near term. The CVE is not listed in the CISA Known Exploited Vulnerabilities catalog.

1. Obtain Editor credentials: Acquire a Grafana account with the Editor role on a vulnerable instance (versions 13.0.0–13.3.0).
2. Identify target folders: Browse or enumerate Grafana folders where the Editor account has only view access but Git Sync managed resources exist.
3. Craft a provisioning job request: Using the Grafana jobs resource API (e.g., POST /api/v1/provisioning/jobs), construct a request specifying a Git Sync operation (delete, move, push, or pull) targeting a resource in the view-only folder.
4. Submit the API request: Send the crafted request with valid Editor authentication credentials (e.g., API key or session token). The API skips folder permission checks, allowing the operation to proceed.
5. Achieve unauthorized modification: The targeted Git Sync resource is deleted, moved, pushed, or pulled without the required folder-level authorization, resulting in unauthorized integrity impact on the Grafana provisioning configuration (GitHub Advisory, Grafana Advisory).

• Network: Unexpected POST requests to the Grafana jobs resource API (e.g., /api/v1/provisioning/jobs) originating from Editor-role accounts, particularly targeting folders those accounts do not own or administer.
• Logs: Grafana audit logs showing provisioning job creation events by Editor-role users against folders where they hold only view permissions; log entries for Git Sync operations (delete, move, push, pull) not initiated by administrators.
• Application Behavior: Unexpected changes to Git Sync managed resources (dashboards, datasources, alert rules) in restricted folders — including missing, moved, or altered resources — without corresponding admin activity.

Grafana has released patched versions addressing this vulnerability: 13.0.13 (for 13.0.x), 13.1.10 (for 13.1.x), 13.2.6 (for 13.2.x), and 13.3.1 (for 13.3.x). Organizations should upgrade to the appropriate patched release as the primary remediation. As interim mitigations, restrict Editor role assignments to only users who require them, monitor the jobs resource API for anomalous provisioning job creation, and consider network-level controls to limit API access to trusted clients (Grafana Advisory, GitHub Advisory).
