Overview

parse-server is a version of the Parse backend that can be deployed to any infrastructure that can run Node.js.

Affected versions of this package are vulnerable to Exposure of Sensitive System Information to an Unauthorized Control Sphere via the handleLogIn and verifyPassword user re-fetch paths in UsersRouter. An attacker can obtain raw _User fields, including MFA secrets and protected fields such as phone, by sending /login or /verifyPassword requests for an account whose _User get class-level permission denies the re-fetch. When the re-fetch is denied, the response exposes stored authData and other hidden user properties, rather than only the authenticated identity, thereby leaking MFA material and other restricted account data to the caller.
