IDOR in GraphQL userCollection Query Exposes Other Users' Private Collections

hoppscotch is an open source API development ecosystem. Prior to version 2026.2.0, the userCollection GraphQL query accepts an arbitrary collection ID and returns the full collection data — including title, type, and the serialized data field containing HTTP requests with headers and potentially secrets — to any authenticated user, without verifying that the requesting user owns the collection. This is an Insecure Direct Object Reference (IDOR) caused by a missing authorization check that exists on every other operation in the same resolver. Version 2026.2.0 fixes the issue.
