CVE-2026-34215

parse-community parse-server

Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.63 and 9.7.0-alpha.7, 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. This issue has been patched in versions 8.6.63 and 9.7.0-alpha.7.
