title: GitOps Run allows for Kubernetes workload injection
description: Weave GitOps is a simple open source developer platform for people who want cloud native applications, without needing Kubernetes expertise.  A vulnerability in GitOps run could allow a local user or process to alter a Kubernetes cluster's resources. GitOps run has a local S3 bucket which it uses for synchronizing files that are later applied against a Kubernetes cluster. Its endpoint had no security controls to block unauthorized access, therefore allowing local users (and processes) on the same machine to see and alter the bucket content. By leveraging this vulnerability, an attacker could pick a workload of their choosing and inject it into the S3 bucket, which resulted in the successful deployment in the target cluster, without the need to provide any credentials to either the S3 bucket nor the target Kubernetes cluster. There are no known workarounds for this issue, please upgrade. This vulnerability has been fixed by commits 75268c4 and 966823b. Users should upgrade to Weave GitOps version >= v0.12.0 released on 08/12/2022.
### Workarounds
