CVE-2026-44478 Details
Description
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.
A vulnerability in Hoppscotch's self-hosted backend versions 2025.7.0 prior to 2026.4.0 allows unauthenticated users to access all infrastructure secrets in plaintext through the GET /v1/onboarding/config endpoint. This issue arises when the ONBOARDING_RECOVERY_TOKEN in the database is empty, enabling a bypass of token validation and exposing sensitive configuration details such as OAuth client IDs and secrets, SMTP credentials, and other private data.
Users can update to Hoppscotch version 2026.4.0 or later to address this vulnerability.
