What is CVE-2026-97063?

The X-SpringBoot framework through version 6.0 is vulnerable to an authentication bypass issue where login verification codes are incorrectly returned in HTTP responses from unauthenticated endpoints such as /sys/mobile/code and /sys/email/code. These codes can be requested by attackers using known mobile numbers or email addresses. Once acquired, attackers can use these codes to gain unauthorized access by authenticating as victims through the endpoint /sys/emailOrMobileLogin/login, leading to potential account takeover.

Affected Version(s)

X-SpringBoot 0 <= 6.0
