CVE-2026-59720 Details
Description
Hoppscotch is an open source API development ecosystem. Prior to 2026.6.0, mock server creation in mock-server.service.ts does not persist the isPublic input field while schema.prisma defaults isPublic to true, causing mock servers linked to private collections to be publicly accessible without authentication and potentially expose sensitive API data. This issue is fixed in version 2026.6.0.
A security misconfiguration in Hoppscotch prior to version 2026.6.0 allows private collection data to be exposed publicly through mock servers. The issue arises because the 'isPublic' field is not properly utilized during mock server creation, leading to a default value of 'true'. Consequently, mock servers associated with private collections become publicly accessible without authentication, potentially revealing sensitive API data such as API keys, user information, and internal endpoints.
Users can update to Hoppscotch version 2026.6.0, where this vulnerability has been fixed. Instructions for updating can be found in the Hoppscotch GitHub repository.
