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
PenguinMod-BackendApi is the backend api for penguinmod. Prior to version 1.0.0, a NoSQL injection vulnerability in the password reset endpoint allows any authenticated user to change the password of an account, leading to full account takeover. An attacker only needs a registered account and a valid password reset token for their own account. This issue has been patched in version 1.0.0.

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

A NoSQL injection vulnerability in the password reset endpoint of PenguinMod-BackendApi allows any authenticated user to manipulate the password reset process and change passwords for arbitrary accounts, enabling full account takeover. The attacker only needs a registered account and a valid password reset token for their own account.

MitigationUpgrade to version 1.0.0 which contains the patch. Additionally, implement proper input validation and parameterized queries to prevent NoSQL injection in the password reset endpoint.

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 PenguinMod-BackendApi installation
    Locate the PenguinMod-BackendApi application in your environment and confirm it is running
    Affected if The application is present and is PenguinMod-BackendApi
  2. Check the installed version
    Run 'npm list penguinmod-backendapi' or check package.json to determine the version number, then compare to 1.0.0
    Affected if The installed version is below 1.0.0
  3. Verify password reset endpoint exists
    Check if the password reset endpoint (typically /api/auth/reset-password or similar) is exposed in the application routes
    Affected if The password reset endpoint is exposed and accessible to authenticated users
  4. Confirm NoSQL database is in use
    Inspect the application configuration to determine if MongoDB or another NoSQL database is used for user authentication
    Affected if A NoSQL database is being used for the backend
  5. Check if input validation is present on password reset
    Review the password reset endpoint code or configuration for presence of input validation and parameterized queries
    Affected if No input validation or parameterized queries are implemented on the password reset endpoint

You are affected if PenguinMod-BackendApi is running with a version below 1.0.0 and the password reset endpoint with NoSQL database lacks proper input validation.

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

Upgrade to version 1.0.0 which contains the patch. Additionally, implement proper input validation and parameterized queries to prevent NoSQL injection in the password reset endpoint.

Recommended fix Moderate confidence

version 1.0.0

  1. 1. Identify the currently deployed version of PenguinMod-BackendApi
  2. 2. Check if the deployed version is prior to version 1.0.0
  3. 3. Upgrade the PenguinMod-BackendApi deployment to version 1.0.0 or later to apply the patched code
