What is CVE-2026-100192?

X-SpringBoot up to version 6.0 has a vulnerability in its application manager functionality that exposes sensitive appKey and appSecret credentials via an unauthenticated GET request. The flaw allows unauthorized attackers to access these credentials through the /application/manager/select endpoint, enabling them to dispatch arbitrary SMS messages using any associated tenant's SMS provider. This could lead to severe consequences like SMS bombing and impersonation attacks without proper safeguards.

Affected Version(s)

X-SpringBoot 0 <= 6.0
