Versions of parse-server prior to 3.6.0 could allow an account enumeration attack via account linking. `ParseError.ACCOUNT_ALREADY_LINKED(208)` was thrown BEFORE the AuthController checks the password and throws a `ParseError.SESSION_MISSING(206)` for Insufficient auth. An attacker can guess ids and get information about linked accounts/email addresses. ### For more information If you have any questions or comments about this advisory, Open an issue in the [parse-server](https://github.com/parse-community/parse-server) [Parse Community Vulnerability Disclosure Program](https://github.com/parse-community/parse-server/blob/master/SECURITY.md)
