Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

In hoppscotch versions before 2026.4.0, the GET /v1/onboarding/config endpoint returns all infrastructure secrets in plaintext to unauthenticated users when the ONBOARDING_RECOVERY_TOKEN in the database is an empty string, allowing unauthenticated attackers to steal sensitive infrastructure credentials.

MitigationUpgrade hoppscotch to version 2026.4.0 or later to remediate this vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify hoppscotch version
    Check the installed version of hoppscotch (typically in package.json, docker image tag, or the application UI footer). Compare it to the affected range: versions before 2026.4.0
    Affected if The installed version is any version prior to 2026.4.0
  2. Verify database connection
    Connect to the hoppscotch database and query the configuration table or wherever ONBOARDING_RECOVERY_TOKEN is stored
    Affected if The ONBOARDING_RECOVERY_TOKEN value in the database is an empty string or null
  3. Check endpoint accessibility
    Send a GET request to /v1/onboarding/config without providing any authentication credentials
    Affected if The endpoint responds without requiring authentication and exposes secret values in the response body

You are affected if running hoppscotch version before 2026.4.0 AND the ONBOARDING_RECOVERY_TOKEN in the database is empty, which allows unauthenticated access to the /v1/onboarding/config endpoint revealing secrets.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade hoppscotch to version 2026.4.0 or later to remediate this vulnerability.

Recommended fix Moderate confidence

2026.4.0

  1. Identify current Hoppscotch installation version by checking the deployed release tag or package.json
  2. If running a version between 2026.2.0 and 2026.3.x inclusive, plan for upgrade
  3. Backup the database and configuration files before upgrading
  4. Upgrade Hoppscotch to version 2026.4.0 or later
  5. After upgrade, verify the GET /v1/onboarding/config endpoint no longer returns plaintext secrets to unauthenticated users
  6. Ensure ONBOARDING_RECOVERY_TOKEN is set to a non-empty value in the database configuration
