This vulnerability exists 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.). CWE classification: CWE-862 (Missing Authorization). --- ## Summary Nuclio Dashboard correctly enforces OPA-based authorization on the project read path (`GET /api/projects`), populating `MemberIds` in `PermissionOptions` so OPA can filter results by user membership. However, the write paths (`PUT /api/projects/{id}` and `DELETE /api/projects`) construct `PermissionOptions` without setting `MemberIds`. The platform-layer `FilterProjectsByPermissions` function (`pkg/platform/abstract/platform.go:652`) short-circuits when `MemberIds` is empty, bypassing OPA entirely. Any authenticated user who knows a project name can modify or delete that project, triggering cascading deletion of all associated Functions, APIGateways, and FunctionEvents. Affected: Nuclio v1.15.26 (latest Helm release) and HEAD commit e185454 (latest source). ---
03 / Response
What to do next
- investigate
Identify the exact component and deployed version, examine the linked publisher’s conditions, and retain evidence of any mitigation.
Confirm current vendor support, compatibility and deployment evidence. This report has not tested a fix in your system. GitHub Advisory Database
A fixed release is not deployment evidence.
Check current vendor support and compatibility. After making a change, verify the deployed build and relevant runtime conditions. Keep the evidence, owner and time. An updated lockfile alone does not prove what is running.
