## How to fix

- Fixed in 0.6.3

## Technical details

The DELETE /v1/appspace/app endpoint fails to enforce proper authorization checks on the appId parameter, allowing authenticated users to delete applications belonging to other tenants. An attacker can enumerate sequential application IDs to discover and remove victims' agents, RAG applications, workflows, and associated data. This is an authorization bypass requiring valid authentication but no special privileges.
