Detailsinfo

A vulnerability, which was classified as critical, was found in hoppscotch. Affected is the function GqlUser. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

hoppscotch is an open source API development ecosystem. Prior to version 2026.2.0, any logged-in user can read, modify or delete another user's personal environment by ID. `user-environments.resolver.ts:82-109`, `updateUserEnvironment` mutation uses `@UseGuards(GqlAuthGuard)` but is missing the `@GqlUser()` decorator entirely. The user's identity is never extracted, so the service receives only the environment ID and performs a `prisma.userEnvironment.update({ where: { id } })` without any ownership filter. `deleteUserEnvironment` does extract the user but the service only uses the UID to check if the target is a global environment. Actual delete query uses WHERE { id } without AND userUid. hoppscotch environments store API keys, auth tokens and secrets used in API requests. An authenticated attacker who obtains another user's environment ID can read their secrets, replace them with malicious values or delete them entirely. The environment ID format is CUID, which limits mass exploitation but insider threat and combined info leak scenarios are realistic. Version 2026.2.0 fixes the issue.

The advisory is available at github.com. This vulnerability is traded as CVE-2026-28216 since 02/25/2026. The exploitability is told to be easy. It is possible to launch the attack remotely. Technical details are known, but there is no available exploit.

Upgrading to version 2026.2.0 eliminates this vulnerability. The upgrade is hosted for download at github.com.
