BIT-parse-2026-33627 — Parse Server: Auth data exposed via /users/me endpoint

2026-10-06T15:35:53.428022+00:00

Affected: Bitnami: parse

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, 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

GHSA-37mj-c2wf-cx96 — Parse Server exposes auth data via /users/me endpoint

2026-10-06T15:35:53.428130+00:00

Affected: npm: parse-server

### Impact

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.

### Patches

The `/users/me` endpoint now queries the session and user data separately, using the caller's authentication context for the user query so that all security layers apply correctly.

### Workarounds

There is no known workaround.
