What to do

  1. Check which version of parse-server you run against the affected versions below, and install the vendor's latest release.
  2. Read the advisory on github.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to 8.6.14 and 9.5.2-alpha.1, NoSQL injection vulnerability allows an unauthenticated attacker to inject MongoDB query operators via the token field in the password reset and email verification resend endpoints. The token value is passed to database queries without type validation and can be used to extract password reset and email verification tokens. Any Parse Server deployment using MongoDB with email verification or password reset enabled is affected. When emailVerifyTokenReuseIfValid is configured, the email verification token can be fully extracted and used to verify a user's email address without inbox access. This vulnerability is fixed in 8.6.14 and 9.5.2-alpha.1.

The underlying weakness: Improper Neutralization of Special Elements in Data Query Logic

The product generates a query intended to access or manipulate data in a data store such as a database, but it does not neutralize or incorrectly neutralizes special elements that can modify the intended logic of the query.
