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.
-
Confirm ContentMX Content Publisher plugin is installedLocate the plugin in your CMS plugin directory or check the plugins list in the admin panelAffected if The plugin appears in the list of installed plugins
-
Identify the installed version numberAccess the plugin details page in the CMS admin panel or inspect the main plugin file header for the version stringAffected if The version is 1.0.6 or lower (any version up to and including 1.0.6)
-
Locate sensitive endpoints or functionality within the pluginReview the plugin source code for functions handling user data, content management, or administrative actionsAffected if The plugin contains functionality that should require authorization but may lack proper access control checks
-
Verify authorization enforcement on restricted actionsTest accessing sensitive plugin functions with a low-privilege user account or unauthenticated requestAffected if Access is granted when it should be denied based on user role or permission level
-
Inspect access control configurationExamine the plugin code for role-based access control (RBAC) implementations and verify all sensitive functions enforce permission checksAffected if Some functions bypass or missing the authorization verification logic
You are affected if the ContentMX Content Publisher plugin version is 1.0.6 or lower and sensitive functionality lacks proper authorization enforcement based on user roles and permissions.

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 on all sensitive endpoints and functionality within the plugin. Review and correct access control security levels to ensure users can only access resources and actions permitted by their assigned roles and permissions.
