SpringBlade vulnerabilities

An XXE vulnerability in the /designer/loadReport endpoint of SpringBlade v4.8.0 allows authenticated attackers to execute arbitrary code via injecting a crafted payload.

In SpringBlade version 3.7.0 and earlier, a missing permission control framework allows a remote attacker to escalate privileges.

A vulnerability was determined in chillzhuang SpringBlade up to 5.0.1. This affects an unknown function of the file RoleController.java in the component User Detail Endpoint. Manipulation of the argument ID causes improper authorization. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet.

A vulnerability was found in chillzhuang SpringBlade up to 5.0.1 in ParamController.java within the Parameter Submit Management component. Manipulation of the initPassword argument results in improper authorization. The attack can be launched remotely and the exploit has been made public.

A vulnerability in chillzhuang SpringBlade up to 5.0.2 affects the UserServiceImpl.userInfo function in the user-auth-info Endpoint component. Manipulation of the userId argument causes authorization bypass, allowing remote attack.

SpringBlade versions from 2.7.3 up to but not including 5.0.0 contain a privilege escalation vulnerability that allows authenticated attackers to create system administrator accounts by sending crafted POST requests to an unprotected internal Feign user-creation endpoint exposed via @RestController without authorization checks. Attackers can exploit the gateway's authentication filter, which only validates JWT parsing without verifying user roles or caller identity, and leverage a hardcoded JWT signing key embedded in publicly available JARs to forge tokens and escalate privileges from a low-privilege user to administrator, enabling cross-tenant data pollution and persistent backdoor access.
