- Weakness
- CWE-200 Exposure of Sensitive Information to an Unauthorized Actor
- Fix
9.7.0-alpha.7- Upgrade parse-server to this version or later
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.
Affected versions
npm
| Package | Vulnerable | Fixed in |
|---|---|---|
| parse-server | >= 9.0.0, < 9.7.0-alpha.7 |
9.7.0-alpha.7 |
| parse-server | < 8.6.63 |
8.6.63 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
parse-server npm → 9.7.0-alpha.7
- npm
npm install parse-server@9.7.0-alpha.7- yarn
yarn add parse-server@9.7.0-alpha.7- pnpm
pnpm add parse-server@9.7.0-alpha.7

Weakness
CWE-200: Exposure of Sensitive Information to an Unauthorized Actor
The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information.
How to prevent it
- Architecture and Design: Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area. Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
