Deeper analysis
CVE-2025-70986 is an incorrect access control vulnerability in the selectDept function of RuoYi version 4.8.2. This flaw allows unauthorized attackers to arbitrarily access sensitive department data. The vulnerability is associated with CWE-284 (Improper Access Control) and CWE-862 (Missing Authorization), and it has a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N), indicating high confidentiality impact with no requirements for privileges or user interaction.
Attackers can exploit this vulnerability remotely over the network with low complexity and no authentication. Any unauthenticated adversary who can reach the affected RuoYi instance may invoke the selectDept function to retrieve sensitive department data, potentially exposing organizational structures, employee information, or other confidential details without detection or restriction.

Mitigating Controls (NIST 800-53 r5) AI
AC-3 mandates enforcement of approved authorizations for access to information and resources, directly preventing unauthorized attackers from accessing sensitive department data via the flawed selectDept function.
AC-24 requires explicit authorization decisions for access to system resources and aborts unauthorized attempts, countering the missing authorization in selectDept that exposes department data.
AC-6 enforces least privilege to restrict access to only what is necessary for tasks, mitigating arbitrary unauthorized access to sensitive department data in RuoYi v4.8.2.
