dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Brave Popup Builder is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Brave Popup Builder' in the list. Alternatively, check the /wp-content/plugins/ directory for a folder named 'brave-popup-builder' or similar.Affected if The plugin is present in the WordPress installation
