dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate the Visual Header plugin filesNavigate to the WordPress plugins directory (wp-content/plugins/) and search for a folder named 'visual-header' or similar. Check the plugin's main PHP file (usually the primary .php file in the plugin folder) for a version declaration in the plugin header comment block.Affected if The plugin folder exists and contains Visual Header plugin files
-
Identify the installed version numberOpen the main Visual Header plugin PHP file and look for the 'Version:' field in the plugin header comment at the top of the file. Alternatively, view the plugin in the WordPress admin dashboard under Plugins to see the installed version.Affected if The version found is below 1.4 or no version number is displayed (indicating an unpatched pre-release version)
-
Check plugin activation statusIn the WordPress admin dashboard, go to Plugins > Installed Plugins and verify whether Visual Header is currently activated.Affected if The plugin is activated and the version is below 1.4
-
Inspect access control configurationReview the Visual Header plugin settings under its configuration page in the WordPress admin.
