CVE-2026-59720Public exploitNetwork attack vector

Unauthenticated data exposure via ignored privacy setting

Published Jul 9, 2026 · Updated Jul 9, 2026

Improper access control in Hoppscotch before 2026.6.0 allows remote attackers to read private collection data through public mock servers. MockServerService omits the isPublic input when creating the database record, so Prisma applies schema.prisma's true default instead of the requested privacy setting. Exposure begins when an authenticated user creates a mock server for a private collection; subsequent requests need no authentication.
