CVE-2025-66736 — youlai-boot V2.21.1 is vulnerable to Incorrect Access Control

High CVSS 7.1

youlai-boot V2.21.1 is vulnerable to Incorrect Access Control. The importUsers function in SysUserController.java does not perform a permission check on the current user's identity, which may allow regular users to import user data into the database, resulting in an authorization bypass vulnerability.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

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

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
