Parse Server exposes auth data via verify password endpoint

CVE-2026-34215 → View on GitHub ↗ View on CVE.org ↗ View on NVD ↗

Description

Impact

The verify password endpoint returns unsanitized authentication data, including MFA TOTP secrets, recovery codes, and OAuth access tokens. An attacker who knows a user's password can extract the MFA secret to generate valid MFA codes, defeating multi-factor authentication protection.

Patches

The verify password endpoint now sanitizes authentication data through auth adapter hooks before returning the response, consistent with login and user retrieval endpoints.

Workarounds

There is no known workaround.
