    CVE-2026-44478

    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.
