CVE-2026-45730

Nuclio: Missing authorization on project write paths allows any authenticated user to modify or delete any project

8.3 HighFix available

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.

Nuclio: Missing authorization on project write paths allows any authenticated user to modify or delete any project

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).

Attacker Model

Attacker type: Authenticated low-privilege tenant (no membership in the target project)

Initial access:

Holds any valid Nuclio Dashboard credentials
The account has no membership in the target project (OPA correctly denies GET /api/projects, returning an empty list)
No Kubernetes RBAC permissions required — the vulnerability is triggered at the Dashboard application layer, not via K8s API Server

Attacker location: Authenticated user; network position depends on deployment:

Typical Iguazio/MLRun enterprise deployment: Dashboard is exposed via load balancer to internal or public networks
Self-hosted deployment: Dashboard is usually limited to cluster-internal or internal network access
Conservative baseline: authenticated-internal; for public-facing deployments, reachability should be rated higher

User interaction required: None

The attacker directly sends HTTP requests to PUT /api/projects/{id} or DELETE /api/projects to trigger the vulnerability; no action from the target user is required

Privilege gap:

Before: Authenticated account with zero permissions on target project
        (OPA correctly denies GET, returns empty list)
   ↓
After:  Can modify or delete any project on the platform
        Can trigger cascading deletion of all associated Functions,
        APIGateways, and FunctionEvents
        Can modify project configuration, affecting NuclioProject CRD
        in Kubernetes deployments

Exploitation difficulty: Very low — four-step attack chain, each step requiring no special technical skill.

Details

Root Cause

The read and write paths diverge in how they populate PermissionOptions.MemberIds:

Read path (correct implementation) — pkg/dashboard/resource/project.go:87-90

PermissionOptions: opaclient.PermissionOptions{
    MemberIds:           opa.GetUserAndGroupIdsFromAuthSession(pr.getCtxSession(ctx)),
    OverrideHeaderValue: request.Header.Get(headers.ProjectsRole),
},

Write path Update (vulnerable) — pkg/dashboard/resource/project.go:194-196

PermissionOptions: opaclient.PermissionOptions{
    OverrideHeaderValue: request.Header.Get(headers.ProjectsRole),
    // MemberIds is not set — OPA check will be skipped
},

PermissionOptions: opaclient.PermissionOptions{

},

Short-circuit bypass — pkg/platform/abstract/platform.go:652
