Vulnerability Title
OpenChoreo: Cross-project command execution and wirelog view access via OpenChoreo openchoreo-api exec and wirelogs endpoints
Source: CVE Program / CVE List V5
Vulnerability Description
OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.1.6 and 1.2.3, internal/openchoreo-api/api/handlers/exec.go and internal/openchoreo-api/api/handlers/wirelogs.go authorize component:exec and wirelogs:view using the caller-supplied project query parameter instead of comp.Spec.Owner.ProjectName, allowing a user with a project-scoped grant to execute commands in and read wirelogs from components owned by other projects in the same namespace. This vulnerability is fixed in 1.1.6 and 1.2.3.
