Information disclosure in Parse Server - CVE-2026-53725

Detailed vulnerability description

The vulnerability allows a remote user to disclose sensitive information.

The vulnerability exists due to exposure of sensitive information in the /login and /verifyPassword endpoints when re-fetching the user through the access-controlled query pipeline after successful password verification. A remote user can submit valid username and password credentials to disclose sensitive information.

Only applications that enable MFA and deny get access on the _User class via class-level permissions are affected. When protectedFieldsOwnerExempt is false, fields hidden by protectedFields may also be exposed. The /verifyPassword endpoint can return MFA TOTP secrets and recovery codes without requiring a session or MFA token.
