Official description

Parse Server before 8.6.97 and 9.0.0 before 9.10.2-alpha.6 does not handle errors raised while sending verification or password reset emails, causing the server process to exit. A client holding only the public application keys can sign up, request a verification email, or request a password reset while the mail provider rejects, rate limits, or is unavailable, crashing the server.
