CVE-2025-55948 — Yzcheng90 X-Springboot security vulnerability

High CVSS 7.3

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.

Privilege escalation and unsafe privilege management

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
  • Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
  • Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.

Remediate safely

  • Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
  • Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
  • Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
