Aug 18, 2026Hoppscotch is an open source API development ecosystem.CVE-2026-69189 · Other software · hoppscotch · reported by GitHubHigh 7.6
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.

Hoppscotch is an open source API development ecosystem. Prior to 2026.6.0, the updateInfraConfigs GraphQL mutation in admin/infra.resolver.ts accepts an attacker-controlled MAILER_SMTP_URL value, and validateSMTPUrl in utils.ts permits path, query, or fragment content that nodemailer parses into sendmail transport options, allowing an admin to execute arbitrary commands as root in the backend container after restart and mail sending. This issue is fixed in version 2026.6.0.

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.

Jul 1, 2026Hoppscotch is an API development ecosystem.CVE-2026-50160 · Other software · hoppscotch · reported by GitHubCritical 10
Hoppscotch is an API development ecosystem. In self-hosted deployments of hoppscotch-backend from version 2026.4.1 and earlier, the unauthenticated POST /v1/onboarding/config endpoint is vulnerable to mass assignment. The global NestJS ValidationPipe is configured without whitelist: true, so extra properties on the request body that are not declared in SaveOnboardingConfigRequest are not stripped and are iterated in the service layer as if they were legitimate InfraConfig entries. Because keys such as JWT_SECRET and SESSION_SECRET are valid InfraConfigEnum values and are not explicitly rejected during validation, an unauthenticated attacker who can reach a fresh instance before onboarding completes (or when no users exist) can overwrite these values in the database. Overwriting JWT_SECRET gives the attacker control of the JWT signing key, allowing them to forge tokens for any user, including administrators, and results in full server compromise. The issue is fixed in hoppscotch 2026.5.0.

May 13, 2026hoppscotch is an open source API development ecosystem.CVE-2026-44478 · Other software · hoppscotch · reported by GitHubHigh 7.5
hoppscotch is an open source API development ecosystem. The fix for CVE-2026-28215 in version 2026.2.0 addresses the unauthenticated POST /v1/onboarding/config endpoint by checking onboardingCompleted and canReRunOnboarding before allowing config overwrites. However, GET /v1/onboarding/config still leaks all infrastructure secrets in plaintext to unauthenticated users when the ONBOARDING_RECOVERY_TOKEN stored in the database is an empty string. This vulnerability is fixed in 2026.4.0.

hoppscotch is an open source API development ecosystem. Prior to version 2026.2.0, the `userCollection` GraphQL query accepts an arbitrary collection ID and returns the full collection data — including title, type, and the serialized `data` field containing HTTP requests with headers and potentially secrets — to any authenticated user, without verifying that the requesting user owns the collection. This is an Insecure Direct Object Reference (IDOR) caused by a missing authorization check that exists on every other operation in the same resolver. Version 2026.2.0 fixes the issue.

Feb 26, 2026hoppscotch is an open source API development ecosystem.CVE-2026-28216 · Other software · hoppscotch · reported by GitHubHigh 8.3
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.

Feb 26, 2026hoppscotch is an open source API development ecosystem.CVE-2026-28215 · Other software · hoppscotch · reported by GitHubCritical 9.1
hoppscotch is an open source API development ecosystem. Prior to version 2026.2.0, an unauthenticated attacker can overwrite the entire infrastructure configuration of a self-hosted Hoppscotch instance including OAuth provider credentials and SMTP settings by sending a single HTTP POST request with no authentication. The endpoint POST /v1/onboarding/config has no authentication guard and performs no check on whether onboarding was already completed. A successful exploit allows the attacker to replace the instance's Google/GitHub/Microsoft OAuth application credentials with their own, causing all subsequent user logins via SSO to authenticate against the attacker's OAuth app. The attacker captures OAuth tokens and email addresses of every user who logs in after the exploit. Additionally, the endpoint returns a recovery token that can be used to read all stored secrets in plaintext, including SMTP passwords and any other configured credentials. Version 2026.2.0 fixes the issue.

May 14, 2024The Hoppscotch Browser Extension is a browser extension for Hoppscotch, a community-driven end-to-end open-source API development ecosystem.CVE-2024-34714 · Other software · hoppscotch · reported by GitHubHigh 7.6
The Hoppscotch Browser Extension is a browser extension for Hoppscotch, a community-driven end-to-end open-source API development ecosystem. Due to an oversight during a change made to the extension in the commit d4e8e4830326f46ba17acd1307977ecd32a85b58, a critical check for the origin list was missed and allowed for messages to be sent to the extension which the extension gladly processed and responded back with the results of, while this wasn't supposed to happen and be blocked by the origin not being present in the origin list. This vulnerability exposes Hoppscotch Extension users to sites which call into Hoppscotch Extension APIs internally. This fundamentally allows any site running on the browser with the extension installed to bypass CORS restrictions if the user is running extensions with the given version. This security hole was patched in the commit 7e364b928ab722dc682d0fcad713a96cc38477d6 which was released along with the extension version `0.35`. As a workaround, Chrome users can use the Extensions Settings to disable the extension access to only the origins that you want. Firefox doesn't have an alternative to upgrading to a fixed version.

May 8, 2024@hoppscotch/cli is a CLI to run Hoppscotch Test Scripts in CI environments.CVE-2024-34347 · Other software · hoppscotch · reported by GitHubHigh 8.3
@hoppscotch/cli is a CLI to run Hoppscotch Test Scripts in CI environments. Prior to 0.8.0, the @hoppscotch/js-sandbox package provides a Javascript sandbox that uses the Node.js vm module. However, the vm module is not safe for sandboxing untrusted Javascript code. This is because code inside the vm context can break out if it can get a hold of any reference to an object created outside of the vm. In the case of @hoppscotch/js-sandbox, multiple references to external objects are passed into the vm context to allow pre-request scripts interactions with environment variables and more. But this also allows the pre-request script to escape the sandbox. This vulnerability is fixed in 0.8.0.
