An Insecure Direct Object Reference (IDOR) vulnerability was identified in the `POST /v1/templates` endpoint of the Lunary API, affecting versions up to 0.8.8. This vulnerability allows authenticated users to create templates in another user's project by altering the `projectId` query parameter. The root cause of this issue is the absence of server-side validation to ensure that the authenticated user owns the specified `projectId`. The vulnerability has been addressed in version 1.9.23.

Matched remediation archetype
Authorization bypass, IDOR, and cross-tenant access
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
- Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
- Use synthetic fixtures to compare intended access matrices without accessing another user's real data.
Remediate safely
- Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
- Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
- Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
