CVE-2025-31746
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMissing Authorization vulnerability in Think201 Clients clients allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Clients: from n/a through <= 1.1.4.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA Missing Authorization vulnerability exists in Think201 Clients (version <= 1.1.4) where the application fails to properly enforce authorization checks, allowing attackers to exploit incorrectly configured access control security levels. This could permit unauthorized users to access functionality or data they should not have permissions for.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Think201 Clients versionCheck the installed version of Think201 Clients through the application UI, installer properties, or version file (commonly found in 'About' section, installation directory, or version manifest)Affected if Installed version is 1.1.4 or lower
-
Review access control security level configurationInspect application configuration files or settings panel for access control security level definitions, looking for any misconfigured or overly permissive security level settingsAffected if Access control security levels are set to a level that bypasses authorization checks or are left at default permissive settings
-
Audit sensitive endpoint access controlsTest or review application endpoints that handle sensitive operations (user data, administrative functions, configuration changes) to verify authorization is enforced on eachAffected if Any sensitive endpoint can be accessed or manipulated without proper authorization validation
-
Verify role-based access control enforcementExamine how user roles and permissions are implemented, checking if all critical functions properly validate user permissions before executionAffected if User roles or permissions are not properly enforced, allowing unauthorized access to role-restricted functionality
Your environment is affected if Think201 Clients version is 1.1.4 or lower AND the application has sensitive endpoints or access control configurations that lack proper authorization enforcement.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper authorization validation at all sensitive endpoints and functions, ensuring access control security levels are correctly configured and enforced for all user roles.
