Detailsinfo

A vulnerability classified as critical was found in yzcheng90 SpringBoot 6.0. Affected by this vulnerability is an unknown function of the component Role-Based Access Control. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-284. The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

This vulnerability fundamentally arises from yzcheng90 X-SpringBoot 6.0's implementation of role-based access control (RBAC) through dual dependency on frontend menu systems and backend permission tables, without enforcing atomic synchronization between these components. The critical flaw manifests when frontend menu updates (such as privilege revocation) fail to propagate to the backend permission table in real-time, creating a dangerous desynchronization. While users lose access to restricted functions through the web interface (as UI elements properly disappear), the stale permission records still validate unauthorized API requests when accessed directly through tools like Postman. Attackers exploiting this inconsistency can perform privileged operations including but not limited to: creating high-permission user accounts, accessing sensitive data beyond their clearance level, and executing admin-level commands.

This vulnerability is known as CVE-2025-55948 since 08/16/2025. The exploitation appears to be easy. The attack can be launched remotely. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 12/05/2025). MITRE ATT&CK project uses the attack technique T1068 for this issue.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
