CVE-2026-97368 Details
Description
A weakness has been identified in chillzhuang SpringBlade up to 5.0.2. This affects the function UserServiceImpl.userInfo of the file blade-service/blade-system/src/main/java/org/springblade/system/service/impl/UserServiceImpl.java of the component user-auth-info Endpoint. This manipulation of the argument userId causes authorization bypass. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. CVE-2026-56100 and CVE-2026-36765 are distinct issues. The vendor was contacted early about this disclosure but did not respond in any way.
An authorization bypass vulnerability has been identified in SpringBlade versions through 5.0.2. The issue resides in the UserServiceImpl.userInfo function, specifically within the user-auth-info endpoint. The vulnerability allows an attacker to manipulate the userId argument, bypassing authorization checks. This flaw can be exploited remotely, especially if the endpoint is exposed through gateway routing or direct service access. The vulnerability has been publicly disclosed and could be used for malicious attacks.
The endpoint should be made internal-only and protected with service-to-service authentication. Remove client control over userId and tenantId, allowing only provider-verified uuid and source. Implement account linking as a separate authorized workflow that requires an authenticated session, verified OAuth ownership, tenant validation, and explicit user consent.
