What it is

X-SpringBoot through 6.0 returns login verification codes in HTTP responses from unauthenticated endpoints GET /sys/mobile/code and GET /sys/email/code without sending them to account owners. Attackers can request codes using known mobile numbers or email addresses, read them from responses, and authenticate as victims via POST /sys/emailOrMobileLogin/login to hijack accounts.
