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.
The verify password endpoint now sanitizes authentication data through auth adapter hooks before returning the response, consistent with login and user retrieval endpoints.
There is no known workaround.
