Description Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.61 and 9.6.0-alpha.55, an authenticated user calling GET /users/me receives unsanitized auth data, including sensitive credentials such as MFA TOTP secrets and recovery codes. The endpoint internally uses master-level authentication for the session query, and the master context leaks through to the user data, bypassing auth adapter sanitization. An attacker who obtains a user's session token can extract MFA secrets to generate valid TOTP codes indefinitely. This issue has been patched in versions 8.6.61 and 9.6.0-alpha.55.
A vulnerability exists in Parse Server versions 8.6.61 prior to 9.6.0-alpha.55, where an authenticated user can access unsanitized authentication data through the '/users/me' endpoint. This data includes sensitive information such as Multi-Factor Authentication (MFA) Time-Based One-Time Password (TOTP) secrets and recovery codes. The issue arises because the endpoint uses master-level authentication to query session data, which inadvertently leaks through to user data, bypassing necessary authentication sanitization. As a result, an attacker with a user's session token can indefinitely generate valid TOTP codes by extracting the MFA secrets.
Users can upgrade to Parse Server versions 8.6.61 or 9.6.0-alpha.55, where this vulnerability has been patched.
