What is CVE-2026-28216?

Hoppscotch, an open-source API development ecosystem, contains a vulnerability that allows any logged-in user to read, modify, or delete another user's personal environment by ID. The issue arises from the misuse of guards and the lack of a GqlUser decorator in the updateUserEnvironment mutation, resulting in no ownership checks on user environments. This flaw enables an authenticated attacker to manipulate sensitive data, including API keys and authentication tokens, leading to potential data breaches. The vulnerability primarily affects environments identified by their IDs and is mitigated in version 2026.2.0.
