This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
