CVE-2026-34215 parse-community CVE debrief

Who should care

Users of Parse Server, especially those who have enabled multi-factor authentication, should be aware of this vulnerability and take immediate action to patch their installations. This includes reviewing and updating authentication configurations to ensure multi-factor authentication is properly implemented and monitoring for suspicious activity related to authentication and authorization.

Technical summary

The verify password endpoint in Parse Server 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. Affected deployments should be updated to these versions to prevent exploitation.
