Information Disclosure in Hoppscotch API Development Ecosystem

Publication date: 2026-08-18

Last updated on: 2026-08-18

Assigner: GitHub, Inc.

Description
Hoppscotch is an open source API development ecosystem. Prior to 2026.6.0, the team, teamMembers.user, RESTHistory, GQLHistory, currentRESTSession, currentGQLSession, environments, globalEnvironments, and settings GraphQL paths expose another workspace member's private User data, while toggleHistoryStarStatus and removeRequestFromHistory in the UserHistory service accept another user's history identifier without enforcing userUid ownership, allowing an authenticated workspace member to read private request history, session data, request contents, authorization headers, environment values, and settings and to modify or delete the victim's private history entries. This issue is fixed in version 2026.6.0.

Executive Summary

Hoppscotch versions before 2026.6.0 have a vulnerability where certain GraphQL paths expose private user data of other workspace members. This includes request history, session data, authorization headers, environment values, and settings. Additionally, some UserHistory service functions allow modifying or deleting another user's private history entries without proper ownership checks.

Impact Analysis

An authenticated workspace member could access sensitive data like request contents, API keys, or environment variables of other users. They could also alter or delete another user's private history entries, potentially disrupting workflows or leaking confidential information.

Compliance Impact

This vulnerability could lead to unauthorized access to personal or sensitive data, violating GDPR's data protection principles or HIPAA's requirements for safeguarding protected health information. Organizations using affected versions may face compliance violations and legal consequences.

Mitigation Strategies

Upgrade Hoppscotch to version 2026.6.0 or later to address the vulnerability. Ensure all workspace members update their instances to prevent unauthorized access to private data and history.
