Summary

Nuclio is a "Serverless" framework for Real-Time Events and Data Processing. Prior to version 1.16.0, there is a vulnerability in Nuclio Dashboard's project management API, allowing any authenticated user (without membership in the target project) to bypass OPA authorization checks on write paths (PUT /api/projects/{id}, DELETE /api/projects) and modify or delete any project along with all its associated resources (functions, API gateways, etc.). This issue has been patched in version 1.16.0.
