[vnets.rs] Subject: [pdm-devel] [PATCH datacenter-manager v2 2/3] fix #6901: api: add explicit permission check for vnets list X-BeenThere: pdm-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox Datacenter Manager development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Reply-To: Proxmox Datacenter Manager development discussion Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: pdm-devel-bounces@lists.proxmox.com Sender: "pdm-devel" When a non-root user tried to access the EVPN section, the API was throwing "403: permission check failed" error. To fix this, add explicit permission check for the `/vnets` endpoint. Now every authenticated user can access the endpoint however, the user needs to have at least `Resource.Audit` permission under `/resource`. Only the vnets from remotes which the user has `Resource.Audit` privilege on `/remote/{remote_name}` will be included in the returned list.
